isn't this extracting the square root
@viniterranova do u mean foil it?
If you quadratic trinomial for (x-1)^2 you will find. x^2+2x+1=9, so x^2+2x-8=0
and that's for the factoring method right???
Pay attetion. Just plug the x´s values +3 and -3 in the (x-1)^2=9. See if this is values are valid for the expression.
x^2+2x-8= 0 ; (x-4)(x+2)=0
well i just wanna be sure
Just solve the expression (x-4)(x+2)=0.
wait, im not there yet, so you move the 9 to the other side, and foil (x-1)^2 and I got x^2-2x+1?
Just pass the 8 for the first term of the equation and subtract it. and you got x^2+2x-8= 0
is thiscorrect

isn't it a -2x
Yes, it´s -2x. Sorry for my lack of attention. So, the expression is x^2-2x-8=0
and are the answers I got correct?
@Skaematik can u check my work
@viniterranova I saw ur work, I understand now
