Simplifying (x + -1a)(x + -3) = 0 Reorder the terms: (-1a + x)(x + -3) = 0 Reorder the terms: (-1a + x)(-3 + x) = 0 Multiply (-1a + x) * (-3 + x) (-1a * (-3 + x) + x(-3 + x)) = 0 ((-3 * -1a + x * -1a) + x(-3 + x)) = 0 ((3a + -1ax) + x(-3 + x)) = 0 (3a + -1ax + (-3 * x + x * x)) = 0 (3a + -1ax + (-3x + x2)) = 0 (3a + -1ax + -3x + x2) = 0 Solving 3a + -1ax + -3x + x2 = 0 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '3x' to each side of the equation. 3a + -1ax + -3x + 3x + x2 = 0 + 3x Combine like terms: -3x + 3x = 0 3a + -1ax + 0 + x2 = 0 + 3x 3a + -1ax + x2 = 0 + 3x Remove the zero: 3a + -1ax + x2 = 3x Add '-1x2' to each side of the equation. 3a + -1ax + x2 + -1x2 = 3x + -1x2 Combine like terms: x2 + -1x2 = 0 3a + -1ax + 0 = 3x + -1x2 3a + -1ax = 3x + -1x2 Reorder the terms: 3a + -1ax + -3x + x2 = 3x + -3x + -1x2 + x2 Combine like terms: 3x + -3x = 0 3a + -1ax + -3x + x2 = 0 + -1x2 + x2 3a + -1ax + -3x + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 3a + -1ax + -3x + x2 = 0 The solution to this equation could not be determined.
