simplify completely
ok, what would the first step be @AriPotta do you know? If not, let me know, and i'll get you through it step by step :)
Just factor and cancel
would it be to find the gcf?
@Hero ,let her figure it out :)
@AriPotta , as hero said, first factor the top part
follow hero's advice
ignore the rest of the people
2(x^2 + 10x + 16)?
10 and 16 8+2 and 8x2
so the x^2s would cancel
wait
erg?
no, that's not true. you want to factor the top and the bottom then
by factoring, you will get 2*(x+2)*(x+8) on the top, and (x-10)*(x+8)
do you understand how to get to that step?
i guess ._.
ok, if i asked you to factor \[x ^{2}+8x+16\] how would you do it?
First try factoring the top and bottom and see if anything cancels out.\[\frac{ 2(x^2+10x+16) }{ x^2-2x-80 }=\frac{ 2(x+2)\cancel{(x+8)} }{ (x-10)\cancel{(x+8)} }=\frac{ 2(x+2) }{ (x-10) }\] @AriPotta
So I first factored out the two. Then I factored the quadratics in the numerator and denominator. Cancelled out x + 8, and the remaining expression is the simplest form it can take. Do you understand? @AriPotta
ok...thanks
