Simplifying 3x2 + -7a + 2a2 = 0 Reorder the terms: -7a + 2a2 + 3x2 = 0 Solving -7a + 2a2 + 3x2 = 0 Solving for variable 'a'. Factor a trinomial. (a + -3x)(2a + -1x) = 0Subproblem 1
Set the factor '(a + -3x)' equal to zero and attempt to solve: Simplifying a + -3x = 0 Solving a + -3x = 0 Move all terms containing a to the left, all other terms to the right. Add '3x' to each side of the equation. a + -3x + 3x = 0 + 3x Combine like terms: -3x + 3x = 0 a + 0 = 0 + 3x a = 0 + 3x Remove the zero: a = 3x Simplifying a = 3xSubproblem 2
Set the factor '(2a + -1x)' equal to zero and attempt to solve: Simplifying 2a + -1x = 0 Solving 2a + -1x = 0 Move all terms containing a to the left, all other terms to the right. Add 'x' to each side of the equation. 2a + -1x + x = 0 + x Combine like terms: -1x + x = 0 2a + 0 = 0 + x 2a = 0 + x Remove the zero: 2a = x Divide each side by '2'. a = 0.5x Simplifying a = 0.5xSolution
a = {3x, 0.5x}
