Simplifying 2x2 + 5x2 = x2 + 30x Combine like terms: 2x2 + 5x2 = 7x2 7x2 = x2 + 30x Reorder the terms: 7x2 = 30x + x2 Solving 7x2 = 30x + x2 Solving for variable 'x'. Reorder the terms: -30x + 7x2 + -1x2 = 30x + x2 + -30x + -1x2 Combine like terms: 7x2 + -1x2 = 6x2 -30x + 6x2 = 30x + x2 + -30x + -1x2 Reorder the terms: -30x + 6x2 = 30x + -30x + x2 + -1x2 Combine like terms: 30x + -30x = 0 -30x + 6x2 = 0 + x2 + -1x2 -30x + 6x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -30x + 6x2 = 0 Factor out the Greatest Common Factor (GCF), '6x'. 6x(-5 + x) = 0 Ignore the factor 6.Subproblem 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 '(-5 + x)' equal to zero and attempt to solve: Simplifying -5 + x = 0 Solving -5 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + x = 0 + 5 Combine like terms: -5 + 5 = 0 0 + x = 0 + 5 x = 0 + 5 Combine like terms: 0 + 5 = 5 x = 5 Simplifying x = 5Solution
x = {0, 5}
