Answer 8

Would you start with the gcf?

Answer 9

yea, but im pretty sure the answer u got it just a simplification, so if thats all you need than i coul walk you through that but...

Answer 10

all i need to do is simplify it

Answer 11

ok, so set X^2-8x+7 equal to 0

now all you need to do is simplify the equation, like before in algebra 1.
and your answer should come out to (X-1)(X-7). then u take that equation and you divide it by (X-7)

Answer 12

so it would be x-1?

Answer 13

yes

Answer 14

thank you
