Simplifying x(2x + -4) = (2x + 5)(x + -7) Reorder the terms: x(-4 + 2x) = (2x + 5)(x + -7) (-4 * x + 2x * x) = (2x + 5)(x + -7) (-4x + 2x2) = (2x + 5)(x + -7) Reorder the terms: -4x + 2x2 = (5 + 2x)(x + -7) Reorder the terms: -4x + 2x2 = (5 + 2x)(-7 + x) Multiply (5 + 2x) * (-7 + x) -4x + 2x2 = (5(-7 + x) + 2x * (-7 + x)) -4x + 2x2 = ((-7 * 5 + x * 5) + 2x * (-7 + x)) -4x + 2x2 = ((-35 + 5x) + 2x * (-7 + x)) -4x + 2x2 = (-35 + 5x + (-7 * 2x + x * 2x)) -4x + 2x2 = (-35 + 5x + (-14x + 2x2)) Combine like terms: 5x + -14x = -9x -4x + 2x2 = (-35 + -9x + 2x2) Add '-2x2' to each side of the equation. -4x + 2x2 + -2x2 = -35 + -9x + 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 -4x + 0 = -35 + -9x + 2x2 + -2x2 -4x = -35 + -9x + 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 -4x = -35 + -9x + 0 -4x = -35 + -9x Solving -4x = -35 + -9x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '9x' to each side of the equation. -4x + 9x = -35 + -9x + 9x Combine like terms: -4x + 9x = 5x 5x = -35 + -9x + 9x Combine like terms: -9x + 9x = 0 5x = -35 + 0 5x = -35 Divide each side by '5'. x = -7 Simplifying x = -7
