F (x) = 2x^3-4x^2+x+8+0+0

Simplifying 2x + 6 = 4x + - 2 Reorder the terms: 6 + 2x = 4x + - 2 Reorder the terms: 6 + 2x = - 2 + 4x Solving 6 + 2x = - 2 + 4x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4x' to each side of the equation. 6 + 2x + - 4x = - 2 + 4x + - 4x Combine like terms: 2x + - 4x = - 2x 6 + - 2x = - 2 + 4x + - 4x Combine like terms: 4x + - 4x = 0 6 + - 2x = - 2 + 0 6 + - 2x = - 2 Add '-6' to each side of the equation. 6 + - 6 + - 2x = - 2 + - 6 Combine like terms: 6 + - 6 = 0 0 + - 2x = - 2 + - 6 - 2x = - 2 + - 6 Combine like terms: - 2 + - 6 = - 8 - 2x = - 8 Divide each side by '-2'. x = 4 Simplifying x = 4
