Wilma and Greg were trying to solve the quadratic equation x^2+bx+c=0
Wilma wrote down the wrong value of b (but her value of c was correct), and found the roots to be 1 and 6. Greg wrote down the wrong value of c (but his value of b was correct), and found the roots to be -1 and -4 What are the actual roots of x^2+bx+c=0?
