Simplifying (7y + -10)(2y + -11) = 0 Reorder the terms: (-10 + 7y)(2y + -11) = 0 Reorder the terms: (-10 + 7y)(-11 + 2y) = 0 Multiply (-10 + 7y) * (-11 + 2y) (-10(-11 + 2y) + 7y * (-11 + 2y)) = 0 ((-11 * -10 + 2y * -10) + 7y * (-11 + 2y)) = 0 ((110 + -20y) + 7y * (-11 + 2y)) = 0 (110 + -20y + (-11 * 7y + 2y * 7y)) = 0 (110 + -20y + (-77y + 14y2)) = 0 Combine like terms: -20y + -77y = -97y (110 + -97y + 14y2) = 0 Solving 110 + -97y + 14y2 = 0 Solving for variable 'y'. Factor a trinomial. (10 + -7y)(11 + -2y) = 0Subproblem 1
Set the factor '(10 + -7y)' equal to zero and attempt to solve: Simplifying 10 + -7y = 0 Solving 10 + -7y = 0 Move all terms containing y to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + -7y = 0 + -10 Combine like terms: 10 + -10 = 0 0 + -7y = 0 + -10 -7y = 0 + -10 Combine like terms: 0 + -10 = -10 -7y = -10 Divide each side by '-7'. y = 1.428571429 Simplifying y = 1.428571429Subproblem 2
Set the factor '(11 + -2y)' equal to zero and attempt to solve: Simplifying 11 + -2y = 0 Solving 11 + -2y = 0 Move all terms containing y to the left, all other terms to the right. Add '-11' to each side of the equation. 11 + -11 + -2y = 0 + -11 Combine like terms: 11 + -11 = 0 0 + -2y = 0 + -11 -2y = 0 + -11 Combine like terms: 0 + -11 = -11 -2y = -11 Divide each side by '-2'. y = 5.5 Simplifying y = 5.5Solution
y = {1.428571429, 5.5}
