Simplifying (2a + -3)(5a + -1) = 0 Reorder the terms: (-3 + 2a)(5a + -1) = 0 Reorder the terms: (-3 + 2a)(-1 + 5a) = 0 Multiply (-3 + 2a) * (-1 + 5a) (-3(-1 + 5a) + 2a * (-1 + 5a)) = 0 ((-1 * -3 + 5a * -3) + 2a * (-1 + 5a)) = 0 ((3 + -15a) + 2a * (-1 + 5a)) = 0 (3 + -15a + (-1 * 2a + 5a * 2a)) = 0 (3 + -15a + (-2a + 10a2)) = 0 Combine like terms: -15a + -2a = -17a (3 + -17a + 10a2) = 0 Solving 3 + -17a + 10a2 = 0 Solving for variable 'a'. Factor a trinomial. (1 + -5a)(3 + -2a) = 0Subproblem 1
Set the factor '(1 + -5a)' equal to zero and attempt to solve: Simplifying 1 + -5a = 0 Solving 1 + -5a = 0 Move all terms containing a to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -5a = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -5a = 0 + -1 -5a = 0 + -1 Combine like terms: 0 + -1 = -1 -5a = -1 Divide each side by '-5'. a = 0.2 Simplifying a = 0.2Subproblem 2
Set the factor '(3 + -2a)' equal to zero and attempt to solve: Simplifying 3 + -2a = 0 Solving 3 + -2a = 0 Move all terms containing a to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -2a = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -2a = 0 + -3 -2a = 0 + -3 Combine like terms: 0 + -3 = -3 -2a = -3 Divide each side by '-2'. a = 1.5 Simplifying a = 1.5Solution
a = {0.2, 1.5}
