Simplifying y(7y + 9) = 0 Reorder the terms: y(9 + 7y) = 0 (9 * y + 7y * y) = 0 (9y + 7y2) = 0 Solving 9y + 7y2 = 0 Solving for variable 'y'. Factor out the Greatest Common Factor (GCF), 'y'. y(9 + 7y) = 0Subproblem 1
Set the factor 'y' equal to zero and attempt to solve: Simplifying y = 0 Solving y = 0 Move all terms containing y to the left, all other terms to the right. Simplifying y = 0Subproblem 2
Set the factor '(9 + 7y)' equal to zero and attempt to solve: Simplifying 9 + 7y = 0 Solving 9 + 7y = 0 Move all terms containing y to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + 7y = 0 + -9 Combine like terms: 9 + -9 = 0 0 + 7y = 0 + -9 7y = 0 + -9 Combine like terms: 0 + -9 = -9 7y = -9 Divide each side by '7'. y = -1.285714286 Simplifying y = -1.285714286Solution
y = {0, -1.285714286}
