Best ResponseYou've already chosen the best response.0it's like this:\[2x^2+3x3=0\] kind of like foiling.

Best ResponseYou've already chosen the best response.0Yes, the opposite of foiling, the unfoiling if you will...

Best ResponseYou've already chosen the best response.0what I do is assume that I can factor and set it up like this: if there is a number in the front (that 2 there) use it for "a" in the following: (x ()/a) (x ()/a)

Best ResponseYou've already chosen the best response.0It is just something to fill in with a number we find.

Best ResponseYou've already chosen the best response.0(x ()/2) (x ()/2) is what I got so far. you with me?

Best ResponseYou've already chosen the best response.0yep, the equation actually tells us how to fill those in, but they are not important in step one.

Best ResponseYou've already chosen the best response.0i converted sin of theta into X

amistre64

Best ResponseYou've already chosen the best response.0X is not important yet; but that little (3) at the end of your equation...how did it get there? was it (a)(b) = 3? or (a)+(b) = (3)

Best ResponseYou've already chosen the best response.0the full equation from the textbook was: \[2\sin ^2 \theta+3\cos \theta3=0\]

Best ResponseYou've already chosen the best response.0we will keep that in mind for later; but fer now, we need to KNOW how that (3) got created. Was it by multiplication or addition?

Best ResponseYou've already chosen the best response.0it was from the textbook. it asks me to find the exact values in degrees

Best ResponseYou've already chosen the best response.0let me ask it this way; in order to "FOIL" to factors together to create the equation . The last term ther , that (3) was made by some process. Was it by adding or multiplying.... think how to "unFOIL" this.

Best ResponseYou've already chosen the best response.0(x + y)(x + y) = xx +xy +xy +yy (x + y)(x + y) = x^2 +2xy +y^2 Is that last term there, that (y^2) made by adding or by multiply 2 numbers together?

Best ResponseYou've already chosen the best response.0umm.. it's plus and minus

amistre64

Best ResponseYou've already chosen the best response.0y^2 = y+y ? or y^2 = y(y) ? (3) = 1 + (3)? or (3) = (1)(3)?

Best ResponseYou've already chosen the best response.0by unfoiling it, i get: \[(2\sin \theta number)(\sin \theta + number)=0\]

Best ResponseYou've already chosen the best response.0I should probably clarify this: Do you want to know HOW to factor? or How to use the quadratic formula to find the answers?

Best ResponseYou've already chosen the best response.0i need to know how to factor the fastest way

amistre64

Best ResponseYou've already chosen the best response.0the fastest way is to use the quadratic formula to find the solutions to a quadratic(a squared) equation.

amistre64

Best ResponseYou've already chosen the best response.0quadratic is a fancy name for: the exponent value of "x" in this equation is a "2".

Best ResponseYou've already chosen the best response.0i meant i want to know how to factor. i'm left with those two numbers. which one should i pick.

amistre64

Best ResponseYou've already chosen the best response.0Ill step you through how I do it :) which works if there are only inegers involved; otherwise, use the quad formula.

amistre64

Best ResponseYou've already chosen the best response.0step1: multiply the first number and the last number to get your actual value that you need to factor to get 2 numbers. In this equation I would that would be: (2)(3) = 6. That is step 1.

amistre64

Best ResponseYou've already chosen the best response.0step 2: setup your factoring into (x....()/a)(x.....()/a). For this equation that would be this: (x ( /2)) (x ( /2)) That is step 2:

Best ResponseYou've already chosen the best response.0step 3: look at the sign of the last term. In this case we have a (3). If the sign is (+); I either need (+)(+) OR ()() If the sign is () I need (+)() this sign of the last number tells me what I am going to use. In your case (3) tells me that I am going to use (+)() step three is done.

Best ResponseYou've already chosen the best response.0step 4: What is the sign of the middle term? In this case we have (+3) This sign tells me that whichever numbers I pick; the largest one is this sign. If it is a () sign on the middle term; the largest number is () If it is a (+) sign on the middle term; the largest number is (+) In your case here; the sign of the middle term (+3) is (+); my biggest number will be positive. Step 4 is done.

Best ResponseYou've already chosen the best response.0step 5: fill in what I already know: (x + ( /2)) (x  (/2)) step 5 is done.

Best ResponseYou've already chosen the best response.0to clarify; in step 5 I used what I knew from YOUR equation that we are using. ok?

Best ResponseYou've already chosen the best response.0ok. i was wondering how to find the numbers. the rest is fine.

amistre64

Best ResponseYou've already chosen the best response.0step 6: take the number we got back in step 1, or simply wait til now to get it :) remember we muliplied the first and last terms. (first)(last) (2)(3) = 6 we factor (6) to get our numbers. 1,6 2,3 Those are all I can get out of it... None of these will subtract to get (+3) 61 = 5 32 = 1 There is no way to use this method to factor your ORIGINAL equation. because we cannot get 2 number that work to fill in our missing stuff. End here and do quad formula.

Best ResponseYou've already chosen the best response.0there are going to be square roots involved; or maybe even no answer. But this method works for any integer value that can be found :)
