Simplifying F(x) = 30x + -5x2 Multiply F * x xF = 30x + -5x2 Solving xF = 30x + -5x2 Solving for variable 'x'. Reorder the terms: -30x + xF + 5x2 = 30x + -5x2 + -30x + 5x2 Reorder the terms: -30x + xF + 5x2 = 30x + -30x + -5x2 + 5x2 Combine like terms: 30x + -30x = 0 -30x + xF + 5x2 = 0 + -5x2 + 5x2 -30x + xF + 5x2 = -5x2 + 5x2 Combine like terms: -5x2 + 5x2 = 0 -30x + xF + 5x2 = 0 Factor out the Greatest Common Factor (GCF), 'x'. x(-30 + 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 '(-30 + F + 5x)' equal to zero and attempt to solve: Simplifying -30 + F + 5x = 0 Solving -30 + F + 5x = 0 Move all terms containing x to the left, all other terms to the right. Add '30' to each side of the equation. -30 + F + 30 + 5x = 0 + 30 Reorder the terms: -30 + 30 + F + 5x = 0 + 30 Combine like terms: -30 + 30 = 0 0 + F + 5x = 0 + 30 F + 5x = 0 + 30 Combine like terms: 0 + 30 = 30 F + 5x = 30 Add '-1F' to each side of the equation. F + -1F + 5x = 30 + -1F Combine like terms: F + -1F = 0 0 + 5x = 30 + -1F 5x = 30 + -1F Divide each side by '5'. x = 6 + -0.2F Simplifying x = 6 + -0.2FSolution
x = {0, 6 + -0.2F}
