Simplifying 8y4 + -50y2 = 0 Reorder the terms: -50y2 + 8y4 = 0 Solving -50y2 + 8y4 = 0 Solving for variable 'y'. Factor out the Greatest Common Factor (GCF), '2y2'. 2y2(-25 + 4y2) = 0 Factor a difference between two squares. 2y2((5 + 2y)(-5 + 2y)) = 0 Ignore the factor 2.Subproblem 1
Set the factor 'y2' equal to zero and attempt to solve: Simplifying y2 = 0 Solving y2 = 0 Move all terms containing y to the left, all other terms to the right. Simplifying y2 = 0 Take the square root of each side: y = {0}Subproblem 2
Set the factor '(5 + 2y)' equal to zero and attempt to solve: Simplifying 5 + 2y = 0 Solving 5 + 2y = 0 Move all terms containing y to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + 2y = 0 + -5 Combine like terms: 5 + -5 = 0 0 + 2y = 0 + -5 2y = 0 + -5 Combine like terms: 0 + -5 = -5 2y = -5 Divide each side by '2'. y = -2.5 Simplifying y = -2.5Subproblem 3
Set the factor '(-5 + 2y)' equal to zero and attempt to solve: Simplifying -5 + 2y = 0 Solving -5 + 2y = 0 Move all terms containing y to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + 2y = 0 + 5 Combine like terms: -5 + 5 = 0 0 + 2y = 0 + 5 2y = 0 + 5 Combine like terms: 0 + 5 = 5 2y = 5 Divide each side by '2'. y = 2.5 Simplifying y = 2.5Solution
y = {0, -2.5, 2.5}
