Simplifying 20y2 = 8y Solving 20y2 = 8y Solving for variable 'y'. Reorder the terms: -8y + 20y2 = 8y + -8y Combine like terms: 8y + -8y = 0 -8y + 20y2 = 0 Factor out the Greatest Common Factor (GCF), '4y'. 4y(-2 + 5y) = 0 Ignore the factor 4.Subproblem 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 '(-2 + 5y)' equal to zero and attempt to solve: Simplifying -2 + 5y = 0 Solving -2 + 5y = 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 + 5y = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 5y = 0 + 2 5y = 0 + 2 Combine like terms: 0 + 2 = 2 5y = 2 Divide each side by '5'. y = 0.4 Simplifying y = 0.4Solution
y = {0, 0.4}
