0 + -7x2 + -8x2 + -1x3 = 0
-7x2 + -8x2 + -1x3 = 0

Combine like terms: -7x2 + -8x2 = -15x2
-15x2 + -1x3 = 0

Solving
-15x2 + -1x3 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), '-1x2'.
-1x2(15 + x) = 0

Ignore the factor -1.

Subproblem 1

Set the factor 'x2' equal to zero and attempt to solve: Simplifying x2 = 0 Solving x2 = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x2 = 0 Take the square root of each side: x = {0}

Subproblem 2

Set the factor '(15 + x)' equal to zero and attempt to solve: Simplifying 15 + x = 0 Solving 15 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-15' to each side of the equation. 15 + -15 + x = 0 + -15 Combine like terms: 15 + -15 = 0 0 + x = 0 + -15 x = 0 + -15 Combine like terms: 0 + -15 = -15 x = -15 Simplifying x = -15

Solution

x = {0, -15}
