Best ResponseYou've already chosen the best response.0If you quadratic trinomial for (x1)^2 you will find. x^2+2x+1=9, so x^2+2x8=0

Best ResponseYou've already chosen the best response.0Pay attetion. Just plug the x´s values +3 and 3 in the (x1)^2=9. See if this is values are valid for the expression.

Best ResponseYou've already chosen the best response.0wait, im not there yet, so you move the 9 to the other side, and foil (x1)^2 and I got x^22x+1?

Best ResponseYou've already chosen the best response.0Just pass the 8 for the first term of the equation and subtract it. and you got x^2+2x8= 0

Best ResponseYou've already chosen the best response.0Yes, it´s 2x. Sorry for my lack of attention. So, the expression is x^22x8=0
