Simplifying 64 = x(2x) Remove parenthesis around (2x) 64 = x * 2x Reorder the terms for easier multiplication: 64 = 2x * x Multiply x * x 64 = 2x2 Solving 64 = 2x2 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2x2' to each side of the equation. 64 + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 64 + -2x2 = 0 Add '-64' to each side of the equation. 64 + -64 + -2x2 = 0 + -64 Combine like terms: 64 + -64 = 0 0 + -2x2 = 0 + -64 -2x2 = 0 + -64 Combine like terms: 0 + -64 = -64 -2x2 = -64 Divide each side by '-2'. x2 = 32 Simplifying x2 = 32 Take the square root of each side: x = {-5.656854249, 5.656854249}
