Simplifying F(x) = -5x2 + 36x Multiply F * x xF = -5x2 + 36x Reorder the terms: xF = 36x + -5x2 Solving xF = 36x + -5x2 Solving for variable 'x'. Reorder the terms: -36x + xF + 5x2 = 36x + -5x2 + -36x + 5x2 Reorder the terms: -36x + xF + 5x2 = 36x + -36x + -5x2 + 5x2 Combine like terms: 36x + -36x = 0 -36x + xF + 5x2 = 0 + -5x2 + 5x2 -36x + xF + 5x2 = -5x2 + 5x2 Combine like terms: -5x2 + 5x2 = 0 -36x + xF + 5x2 = 0 Factor out the Greatest Common Factor (GCF), 'x'. x(-36 + F + 5x) = 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 '(-36 + F + 5x)' equal to zero and attempt to solve: Simplifying -36 + F + 5x = 0 Solving -36 + F + 5x = 0 Move all terms containing x to the left, all other terms to the right. Add '36' to each side of the equation. -36 + F + 36 + 5x = 0 + 36 Reorder the terms: -36 + 36 + F + 5x = 0 + 36 Combine like terms: -36 + 36 = 0 0 + F + 5x = 0 + 36 F + 5x = 0 + 36 Combine like terms: 0 + 36 = 36 F + 5x = 36 Add '-1F' to each side of the equation. F + -1F + 5x = 36 + -1F Combine like terms: F + -1F = 0 0 + 5x = 36 + -1F 5x = 36 + -1F Divide each side by '5'. x = 7.2 + -0.2F Simplifying x = 7.2 + -0.2FSolution
x = {0, 7.2 + -0.2F}
