Simplifying 12y2 + 21y5 = 0 Solving 12y2 + 21y5 = 0 Solving for variable 'y'. Factor out the Greatest Common Factor (GCF), '3y2'. 3y2(4 + 7y3) = 0 Ignore the factor 3.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 '(4 + 7y3)' equal to zero and attempt to solve: Simplifying 4 + 7y3 = 0 Solving 4 + 7y3 = 0 Move all terms containing y to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + 7y3 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + 7y3 = 0 + -4 7y3 = 0 + -4 Combine like terms: 0 + -4 = -4 7y3 = -4 Divide each side by '7'. y3 = -0.5714285714 Simplifying y3 = -0.5714285714 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
y = {0}
