Simplifying (2a + -3)(a + -2) = 0 Reorder the terms: (-3 + 2a)(a + -2) = 0 Reorder the terms: (-3 + 2a)(-2 + a) = 0 Multiply (-3 + 2a) * (-2 + a) (-3(-2 + a) + 2a * (-2 + a)) = 0 ((-2 * -3 + a * -3) + 2a * (-2 + a)) = 0 ((6 + -3a) + 2a * (-2 + a)) = 0 (6 + -3a + (-2 * 2a + a * 2a)) = 0 (6 + -3a + (-4a + 2a2)) = 0 Combine like terms: -3a + -4a = -7a (6 + -7a + 2a2) = 0 Solving 6 + -7a + 2a2 = 0 Solving for variable 'a'. Factor a trinomial. (3 + -2a)(2 + -1a) = 0Subproblem 1
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 = 1.5Subproblem 2
Set the factor '(2 + -1a)' equal to zero and attempt to solve: Simplifying 2 + -1a = 0 Solving 2 + -1a = 0 Move all terms containing a to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -1a = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1a = 0 + -2 -1a = 0 + -2 Combine like terms: 0 + -2 = -2 -1a = -2 Divide each side by '-1'. a = 2 Simplifying a = 2Solution
a = {1.5, 2}
