Simplifying F(x) = 4x2 + 8x Multiply F * x xF = 4x2 + 8x Reorder the terms: xF = 8x + 4x2 Solving xF = 8x + 4x2 Solving for variable 'x'. Reorder the terms: -8x + xF + -4x2 = 8x + 4x2 + -8x + -4x2 Reorder the terms: -8x + xF + -4x2 = 8x + -8x + 4x2 + -4x2 Combine like terms: 8x + -8x = 0 -8x + xF + -4x2 = 0 + 4x2 + -4x2 -8x + xF + -4x2 = 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 -8x + xF + -4x2 = 0 Factor out the Greatest Common Factor (GCF), 'x'. x(-8 + F + -4x) = 0Subproblem 1
Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0Subproblem 2
Set the factor '(-8 + F + -4x)' equal to zero and attempt to solve: Simplifying -8 + F + -4x = 0 Solving -8 + F + -4x = 0 Move all terms containing x to the left, all other terms to the right. Add '8' to each side of the equation. -8 + F + 8 + -4x = 0 + 8 Reorder the terms: -8 + 8 + F + -4x = 0 + 8 Combine like terms: -8 + 8 = 0 0 + F + -4x = 0 + 8 F + -4x = 0 + 8 Combine like terms: 0 + 8 = 8 F + -4x = 8 Add '-1F' to each side of the equation. F + -1F + -4x = 8 + -1F Combine like terms: F + -1F = 0 0 + -4x = 8 + -1F -4x = 8 + -1F Divide each side by '-4'. x = -2 + 0.25F Simplifying x = -2 + 0.25FSolution
x = {0, -2 + 0.25F}
