SUMMARY

The equation x^2 + ax + b = 0 has roots x = -1 and x = 1. By factoring the equation as (x - 1)(x + 1) = 0 and expanding, it simplifies to x^2 - 1 = 0. This leads to the conclusion that the values of a and b are a = 0 and b = -1, confirming the solution is correct.

Homework Statement



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



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,,,, ?
