how do you solve this problem. i'll write it below.
\[x^2-3x-18/ x^2-2x-24\div 1/x+4\]
\[{x^2-3x-18\over x^2-2x-24}\div{1\over x+4}\]
i'm guessing this is the problem: oops too fast form me but that's exactly what i was writing...^^^
did I type it correctly?
thats the right equation
first step is to factor the left side as much as possible
can you factor\[x^2-3x-18\]can you factor\[x^2-2x-24\]?
yeah, give me a sec to work it out.
okay so for the first equation the answer is (x-6)(x-3)
careful (-)(-)=+ so (-6)(-3)=+18 and we want -18
we also want the two numbers to add to the middle term, -3, and -3+(-6)=-9 not -3
(hint: the numbers are right but the signs need adjustment)
I don't know what signs i messed up on. the only numbers i can get is -6 and 3
yes, so it should be (x-6)(x+3)
