Simplifying X(2x + -1) = (2x + 1)(x + -4) Reorder the terms: X(-1 + 2x) = (2x + 1)(x + -4) (-1 * X + 2x * X) = (2x + 1)(x + -4) (-1X + 2xX) = (2x + 1)(x + -4) Reorder the terms: -1X + 2xX = (1 + 2x)(x + -4) Reorder the terms: -1X + 2xX = (1 + 2x)(-4 + x) Multiply (1 + 2x) * (-4 + x) -1X + 2xX = (1(-4 + x) + 2x * (-4 + x)) -1X + 2xX = ((-4 * 1 + x * 1) + 2x * (-4 + x)) -1X + 2xX = ((-4 + 1x) + 2x * (-4 + x)) -1X + 2xX = (-4 + 1x + (-4 * 2x + x * 2x)) -1X + 2xX = (-4 + 1x + (-8x + 2x2)) Combine like terms: 1x + -8x = -7x -1X + 2xX = (-4 + -7x + 2x2) Solving -1X + 2xX = -4 + -7x + 2x2 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Reorder the terms: 4 + -1X + 7x + 2xX + -2x2 = -4 + -7x + 2x2 + 4 + 7x + -2x2 Reorder the terms: 4 + -1X + 7x + 2xX + -2x2 = -4 + 4 + -7x + 7x + 2x2 + -2x2 Combine like terms: -4 + 4 = 0 4 + -1X + 7x + 2xX + -2x2 = 0 + -7x + 7x + 2x2 + -2x2 4 + -1X + 7x + 2xX + -2x2 = -7x + 7x + 2x2 + -2x2 Combine like terms: -7x + 7x = 0 4 + -1X + 7x + 2xX + -2x2 = 0 + 2x2 + -2x2 4 + -1X + 7x + 2xX + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 4 + -1X + 7x + 2xX + -2x2 = 0 The solution to this equation could not be determined.
