Simplifying x2 + (a + -4) * x + -4a = 0 Reorder the terms: x2 + (-4 + a) * x + -4a = 0 Reorder the terms for easier multiplication: x2 + x(-4 + a) + -4a = 0 x2 + (-4 * x + a * x) + -4a = 0 Reorder the terms: x2 + (ax + -4x) + -4a = 0 x2 + (ax + -4x) + -4a = 0 Reorder the terms: -4a + ax + -4x + x2 = 0 Solving -4a + ax + -4x + x2 = 0 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '4x' to each side of the equation. -4a + ax + -4x + 4x + x2 = 0 + 4x Combine like terms: -4x + 4x = 0 -4a + ax + 0 + x2 = 0 + 4x -4a + ax + x2 = 0 + 4x Remove the zero: -4a + ax + x2 = 4x Add '-1x2' to each side of the equation. -4a + ax + x2 + -1x2 = 4x + -1x2 Combine like terms: x2 + -1x2 = 0 -4a + ax + 0 = 4x + -1x2 -4a + ax = 4x + -1x2 Reorder the terms: -4a + ax + -4x + x2 = 4x + -4x + -1x2 + x2 Combine like terms: 4x + -4x = 0 -4a + ax + -4x + x2 = 0 + -1x2 + x2 -4a + ax + -4x + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 -4a + ax + -4x + x2 = 0 The solution to this equation could not be determined.
