Simplifying F(x) = 9x2 + 3x Multiply F * x xF = 9x2 + 3x Reorder the terms: xF = 3x + 9x2 Solving xF = 3x + 9x2 Solving for variable 'x'. Reorder the terms: -3x + xF + -9x2 = 3x + 9x2 + -3x + -9x2 Reorder the terms: -3x + xF + -9x2 = 3x + -3x + 9x2 + -9x2 Combine like terms: 3x + -3x = 0 -3x + xF + -9x2 = 0 + 9x2 + -9x2 -3x + xF + -9x2 = 9x2 + -9x2 Combine like terms: 9x2 + -9x2 = 0 -3x + xF + -9x2 = 0 Factor out the Greatest Common Factor (GCF), 'x'. x(-3 + F + -9x) = 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 '(-3 + F + -9x)' equal to zero and attempt to solve: Simplifying -3 + F + -9x = 0 Solving -3 + F + -9x = 0 Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + F + 3 + -9x = 0 + 3 Reorder the terms: -3 + 3 + F + -9x = 0 + 3 Combine like terms: -3 + 3 = 0 0 + F + -9x = 0 + 3 F + -9x = 0 + 3 Combine like terms: 0 + 3 = 3 F + -9x = 3 Add '-1F' to each side of the equation. F + -1F + -9x = 3 + -1F Combine like terms: F + -1F = 0 0 + -9x = 3 + -1F -9x = 3 + -1F Divide each side by '-9'. x = -0.3333333333 + 0.1111111111F Simplifying x = -0.3333333333 + 0.1111111111FSolution
x = {0, -0.3333333333 + 0.1111111111F}
