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