Simplifying -7y + -6 = 2y2 Reorder the terms: -6 + -7y = 2y2 Solving -6 + -7y = 2y2 Solving for variable 'y'. Combine like terms: 2y2 + -2y2 = 0 -6 + -7y + -2y2 = 0 Factor out the Greatest Common Factor (GCF), '-1'. -1(6 + 7y + 2y2) = 0 Factor a trinomial. -1((2 + y)(3 + 2y)) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(2 + y)' equal to zero and attempt to solve: Simplifying 2 + y = 0 Solving 2 + y = 0 Move all terms containing y to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + y = 0 + -2 Combine like terms: 2 + -2 = 0 0 + y = 0 + -2 y = 0 + -2 Combine like terms: 0 + -2 = -2 y = -2 Simplifying y = -2Subproblem 2
Set the factor '(3 + 2y)' equal to zero and attempt to solve: Simplifying 3 + 2y = 0 Solving 3 + 2y = 0 Move all terms containing y to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + 2y = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 2y = 0 + -3 2y = 0 + -3 Combine like terms: 0 + -3 = -3 2y = -3 Divide each side by '2'. y = -1.5 Simplifying y = -1.5Solution
y = {-2, -1.5}
