(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

If x = -1; 1 are the two roots of the equation x^2 +ax+b = 0; then find the values of a and b.

3. The attempt at a solution

x^2+ax+b=0

(x-1) (x+1)= 0 ,,,,,, by expanding

x^2-1=0 ,,,,, so a=0 , b=-1

is it right or the question is asking for something eles,,,, ?
