Simplifying (g + 9)(g + -2) = 0 Reorder the terms: (9 + g)(g + -2) = 0 Reorder the terms: (9 + g)(-2 + g) = 0 Multiply (9 + g) * (-2 + g) (9(-2 + g) + g(-2 + g)) = 0 ((-2 * 9 + g * 9) + g(-2 + g)) = 0 ((-18 + 9g) + g(-2 + g)) = 0 (-18 + 9g + (-2 * g + g * g)) = 0 (-18 + 9g + (-2g + g2)) = 0 Combine like terms: 9g + -2g = 7g (-18 + 7g + g2) = 0 Solving -18 + 7g + g2 = 0 Solving for variable 'g'. Factor a trinomial. (-9 + -1g)(2 + -1g) = 0Subproblem 1
Set the factor '(-9 + -1g)' equal to zero and attempt to solve: Simplifying -9 + -1g = 0 Solving -9 + -1g = 0 Move all terms containing g to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + -1g = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -1g = 0 + 9 -1g = 0 + 9 Combine like terms: 0 + 9 = 9 -1g = 9 Divide each side by '-1'. g = -9 Simplifying g = -9Subproblem 2
Set the factor '(2 + -1g)' equal to zero and attempt to solve: Simplifying 2 + -1g = 0 Solving 2 + -1g = 0 Move all terms containing g to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -1g = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1g = 0 + -2 -1g = 0 + -2 Combine like terms: 0 + -2 = -2 -1g = -2 Divide each side by '-1'. g = 2 Simplifying g = 2Solution
g = {-9, 2}
