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 8. 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?
+37157 Wilma (x-1)(x-8) = x^2 - 9x + 8 and 8 is correct
Greg (x-1)(x+4) = x^2 + 3x -4 and 3 is correct
then the correct = x^2 + 3x + 8 use quadratic formula x = -3/2 +- sqrt (23)i / 2
