Simplifying X(7x + -1) = (7x + 1)(x + -2) Reorder the terms: X(-1 + 7x) = (7x + 1)(x + -2) (-1 * X + 7x * X) = (7x + 1)(x + -2) (-1X + 7xX) = (7x + 1)(x + -2) Reorder the terms: -1X + 7xX = (1 + 7x)(x + -2) Reorder the terms: -1X + 7xX = (1 + 7x)(-2 + x) Multiply (1 + 7x) * (-2 + x) -1X + 7xX = (1(-2 + x) + 7x * (-2 + x)) -1X + 7xX = ((-2 * 1 + x * 1) + 7x * (-2 + x)) -1X + 7xX = ((-2 + 1x) + 7x * (-2 + x)) -1X + 7xX = (-2 + 1x + (-2 * 7x + x * 7x)) -1X + 7xX = (-2 + 1x + (-14x + 7x2)) Combine like terms: 1x + -14x = -13x -1X + 7xX = (-2 + -13x + 7x2) Solving -1X + 7xX = -2 + -13x + 7x2 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Reorder the terms: 2 + -1X + 13x + 7xX + -7x2 = -2 + -13x + 7x2 + 2 + 13x + -7x2 Reorder the terms: 2 + -1X + 13x + 7xX + -7x2 = -2 + 2 + -13x + 13x + 7x2 + -7x2 Combine like terms: -2 + 2 = 0 2 + -1X + 13x + 7xX + -7x2 = 0 + -13x + 13x + 7x2 + -7x2 2 + -1X + 13x + 7xX + -7x2 = -13x + 13x + 7x2 + -7x2 Combine like terms: -13x + 13x = 0 2 + -1X + 13x + 7xX + -7x2 = 0 + 7x2 + -7x2 2 + -1X + 13x + 7xX + -7x2 = 7x2 + -7x2 Combine like terms: 7x2 + -7x2 = 0 2 + -1X + 13x + 7xX + -7x2 = 0 The solution to this equation could not be determined.
