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