x2 - 2x = 63 x2 - 2x - 63 = 0 Find two factors of -63 that add to -2 (including the sign). These are (-9,7) so, x2 - 9x + 7x - 63 = 0 x*(x-9) + 7*(x-9) = 0 (x-9)*(x+7) = 0 and so x - 9 or x = -7

a2 + 62 = 122 a2 + 62 - 62 = 122 - 62 a2 = 144 - 36 a2 = 108 taking the square root of each side, we get a equal plus or minus the square root of 108, or plus or minus 6 times the square root of 3.
