-4x2 - 32x + x + 8 = 8x2 - 56x : simplify and group the various terms
-32x + 56x + x + 8 = 8x2 + 4x2
25x + 8 = 12x2 : Now present this as a standard quadratic equation.
12x2 - 25x - 8 = 0 : Solving for the roots of a quadratic equation gives :-
x = [25 ± √(252 + 4x12x8)] ÷ 2x12 = [25 ± √1009] ÷ 24 = [25 ± 31.765] ÷ 24
x = 56.765/24 = 2.365 and x = -6.765/24 = -0.282
x = 2.365 and -0.282
