Simplifying F(X) = -2kx2 + -1(k + 3) * x + 30 Multiply F * X FX = -2kx2 + -1(k + 3) * x + 30 Reorder the terms: FX = -2kx2 + -1(3 + k) * x + 30 Reorder the terms for easier multiplication: FX = -2kx2 + -1x(3 + k) + 30 FX = -2kx2 + (3 * -1x + k * -1x) + 30 Reorder the terms: FX = -2kx2 + (-1kx + -3x) + 30 FX = -2kx2 + (-1kx + -3x) + 30 Reorder the terms: FX = 30 + -1kx + -2kx2 + -3x Solving FX = 30 + -1kx + -2kx2 + -3x Solving for variable 'F'. Move all terms containing F to the left, all other terms to the right. Divide each side by 'X'. F = 30X-1 + -1kxX-1 + -2kx2X-1 + -3xX-1 Simplifying F = 30X-1 + -1kxX-1 + -2kx2X-1 + -3xX-1
