teach? dunno.... I can explain tho :)

it's like this:\[2x^2+3x-3=0\] kind of like foiling.

Yes, the opposite of foiling, the unfoiling if you will...

the easy way?

what's () ?

It is just something to fill in with a number we find.

(x ()/2) (x ()/2)
is what I got so far. you with me?

the signs are still invisible, right?

yep, the equation actually tells us how to fill those in, but they are not important in step one.

ok. i'm understanding it a bit more

How is the last term inthe equation made? by addition or multiplication?

i converted sin of theta into X

the full equation from the textbook was:
\[2\sin ^2 \theta+3\cos \theta-3=0\]

it was from the textbook. it asks me to find the exact values in degrees

umm.. it's plus and minus

y^2 = y+y ?
or
y^2 = y(y) ?
(-3) = 1 + (-3)?
or
(-3) = (1)(-3)?

by unfoiling it, i get:
\[(2\sin \theta- number)(\sin \theta + number)=0\]

yea.

i need to know how to factor the fastest way

quadratic is a fancy name for: the exponent value of "x" in this equation is a "2".

i meant i want to know how to factor. i'm left with those two numbers. which one should i pick.

allrights~

ok

step 5: fill in what I already know:
(x + ( /2)) (x - (/2))
step 5 is done.

to clarify; in step 5 I used what I knew from YOUR equation that we are using. ok?

ok. i was wondering how to find the numbers. the rest is fine.

ahh, i get it now. that's the answer i want. thanks
