2x^2 - 12x - 10 = 0 x^2 - 6x - 5 = 0 x^2 - 6x + 9 - 5 = 9 (x - 3)^2 - 5 = 9 (x - 3)^2 = 14 x - 3 = √14 or x - 3 = -√14 x = 3 + √14 or x = 3 - √14

2x^2 - 12 - 10 = 0 2x^2 = 22 x^2 = 11 x = ±√11 If you meant 2x^2 - 12x - 10 = 0, 2(x^2 - 6x - 5) =0 Quadratic formula: x = (-(-6) ± √(36 - 4(-5))) / 2 x = 3 ± √14
