Simplifying x2 + 4x + a = (x + -1)(x + b) Reorder the terms: a + 4x + x2 = (x + -1)(x + b) Reorder the terms: a + 4x + x2 = (-1 + x)(x + b) Reorder the terms: a + 4x + x2 = (-1 + x)(b + x) Multiply (-1 + x) * (b + x) a + 4x + x2 = (-1(b + x) + x(b + x)) a + 4x + x2 = ((b * -1 + x * -1) + x(b + x)) a + 4x + x2 = ((-1b + -1x) + x(b + x)) a + 4x + x2 = (-1b + -1x + (b * x + x * x)) a + 4x + x2 = (-1b + -1x + (bx + x2)) Reorder the terms: a + 4x + x2 = (-1b + bx + -1x + x2) a + 4x + x2 = (-1b + bx + -1x + x2) Add '-1x2' to each side of the equation. a + 4x + x2 + -1x2 = -1b + bx + -1x + x2 + -1x2 Combine like terms: x2 + -1x2 = 0 a + 4x + 0 = -1b + bx + -1x + x2 + -1x2 a + 4x = -1b + bx + -1x + x2 + -1x2 Combine like terms: x2 + -1x2 = 0 a + 4x = -1b + bx + -1x + 0 a + 4x = -1b + bx + -1x Solving a + 4x = -1b + bx + -1x 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. a + 4x + -4x = -1b + bx + -1x + -4x Combine like terms: 4x + -4x = 0 a + 0 = -1b + bx + -1x + -4x a = -1b + bx + -1x + -4x Combine like terms: -1x + -4x = -5x a = -1b + bx + -5x Simplifying a = -1b + bx + -5x
