Simplifying (2 + -1y)(3y + 5) = 0 Reorder the terms: (2 + -1y)(5 + 3y) = 0 Multiply (2 + -1y) * (5 + 3y) (2(5 + 3y) + -1y * (5 + 3y)) = 0 ((5 * 2 + 3y * 2) + -1y * (5 + 3y)) = 0 ((10 + 6y) + -1y * (5 + 3y)) = 0 (10 + 6y + (5 * -1y + 3y * -1y)) = 0 (10 + 6y + (-5y + -3y2)) = 0 Combine like terms: 6y + -5y = 1y (10 + 1y + -3y2) = 0 Solving 10 + 1y + -3y2 = 0 Solving for variable 'y'. Factor a trinomial. (2 + -1y)(5 + 3y) = 0Subproblem 1
Set the factor '(2 + -1y)' equal to zero and attempt to solve: Simplifying 2 + -1y = 0 Solving 2 + -1y = 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 + -1y = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1y = 0 + -2 -1y = 0 + -2 Combine like terms: 0 + -2 = -2 -1y = -2 Divide each side by '-1'. y = 2 Simplifying y = 2Subproblem 2
Set the factor '(5 + 3y)' equal to zero and attempt to solve: Simplifying 5 + 3y = 0 Solving 5 + 3y = 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 + 3y = 0 + -5 Combine like terms: 5 + -5 = 0 0 + 3y = 0 + -5 3y = 0 + -5 Combine like terms: 0 + -5 = -5 3y = -5 Divide each side by '3'. y = -1.666666667 Simplifying y = -1.666666667Solution
y = {2, -1.666666667}
