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