For ax^2+bx+c=0 with a=1, b=-6, c=-16, the quadratic formula gives
x = [−b ± √(b^2 − 4ac)]/(2a) = [6 ± √(36 − 4·1·(−16))]/2 = [6 ± √100]/2 = [6 ± 10]/2.
Thus x = (6+10)/2 = 8 or x = (6−10)/2 = −2.
x = [−b ± √(b^2 − 4ac)]/(2a) = [6 ± √(36 − 4·1·(−16))]/2 = [6 ± √100]/2 = [6 ± 10]/2.
Thus x = (6+10)/2 = 8 or x = (6−10)/2 = −2.
