Best ResponseYou've already chosen the best response.0Distrubute the factors and multiply it out. Then simplify. Treat the inequality just as you would an equal side. The only tricky thing to remember is if you divide by a negative you have to change which way the inequality goes.

Best ResponseYou've already chosen the best response.0lets figure out what I did :) lets start with an easy example... 3(8) = 24 right?

amistre64

Best ResponseYou've already chosen the best response.0then: 3(6+2) should also equal 24 right?

amistre64

Best ResponseYou've already chosen the best response.0then this should also work for us: 3(6) + 3(2) = 24 18 + 6 = 24 24 = 24 .... do you see that? its called the distributive property and it allows us to "distribute" the 3 thru the (6+2) to get the answer.

Best ResponseYou've already chosen the best response.0excellent work..... see how easy that is :)

Best ResponseYou've already chosen the best response.0that left side has one more "distribution" to take care of: 9x(7x28) is what? I know you can do this...

amistre64

Best ResponseYou've already chosen the best response.0look over your "multiplication" work again and try that again.... 9x(7x) +9x(28) ....

Best ResponseYou've already chosen the best response.0i see what mistake i made

Best ResponseYou've already chosen the best response.0very good, but remember to include the "x". x(x) = x^2 ; which means x squared.

Best ResponseYou've already chosen the best response.063x^2 252x ..... ok?

amistre64

Best ResponseYou've already chosen the best response.0that is correct.... 63x^2 252x < 4x 16 3x is what we are up to now.... do you know what we should do now?

amistre64

Best ResponseYou've already chosen the best response.0we can simplify this to some extent yes, we can "combine" like terms..

Best ResponseYou've already chosen the best response.063^2 252x < 4x3x 16 63x^2 252x < x 16 Do you know how to move things from one side to the other? Its important to be able to do this while keeping the balance between them the same.... does that make sense?

Best ResponseYou've already chosen the best response.0yes it makes sense i think i do how to move one side to the the other

Best ResponseYou've already chosen the best response.0let me give you an easy example to remind you: 10 < 15 right? then 1+2+3+4 < 4+5+6 right?

amistre64
 5 years ago
Best ResponseYou've already chosen the best response.0to keep everything in balance...whatever we "add" or "remove" from one side has to be done to the other.... right? lets subtract "4" from each side 1+2+3+4 4 < 4+5+6 4 1+2+3 < 5+6 ; 6>11

Best ResponseYou've already chosen the best response.063x^2 252x < x 16 lets make the lefthand side = 0, to do that we need to "add" their value to both sides

Best ResponseYou've already chosen the best response.063x^2 [+63x^2] 252x [+252x] < [+63x^2] +x [+252x]16

Best ResponseYou've already chosen the best response.00< 63x^2 +253x 16 is what we get right?

Best ResponseYou've already chosen the best response.0now comes the hard part, because it gets a little on the "advanced" side of things for this one..... but we can use a formula called the "quadratic" formula to find the values for "x" that make this equal to zero... wanna try it out?

amistre64

Best ResponseYou've already chosen the best response.0ok.... notive that we have numbers in front of all of our "terms". they are 63, 253, and 16. we want to use these in our quadratic formula....

Best ResponseYou've already chosen the best response.0253 + sqrt(253^2  (4)(16)(63))  2(63) this aint gonna be pretty :)

Best ResponseYou've already chosen the best response.0is sqrt is square rIght?

amistre64

Best ResponseYou've already chosen the best response.0yes, sqrt() is what I use to indicate the square root "umbrella" and everything inside of the () is what is under the "umbrella".
