Simplifying (X + 2)(x + -2) = 21 Reorder the terms: (2 + X)(x + -2) = 21 Reorder the terms: (2 + X)(-2 + x) = 21 Multiply (2 + X) * (-2 + x) (2(-2 + x) + X(-2 + x)) = 21 ((-2 * 2 + x * 2) + X(-2 + x)) = 21 ((-4 + 2x) + X(-2 + x)) = 21 (-4 + 2x + (-2 * X + x * X)) = 21 (-4 + 2x + (-2X + xX)) = 21 Reorder the terms: (-4 + -2X + 2x + xX) = 21 (-4 + -2X + 2x + xX) = 21 Solving -4 + -2X + 2x + xX = 21 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '4' to each side of the equation. -4 + -2X + 2x + 4 + xX = 21 + 4 Reorder the terms: -4 + 4 + -2X + 2x + xX = 21 + 4 Combine like terms: -4 + 4 = 0 0 + -2X + 2x + xX = 21 + 4 -2X + 2x + xX = 21 + 4 Combine like terms: 21 + 4 = 25 -2X + 2x + xX = 25 Add '-2x' to each side of the equation. -2X + 2x + -2x + xX = 25 + -2x Combine like terms: 2x + -2x = 0 -2X + 0 + xX = 25 + -2x -2X + xX = 25 + -2x Reorder the terms: -25 + -2X + 2x + xX = 25 + -2x + -25 + 2x Reorder the terms: -25 + -2X + 2x + xX = 25 + -25 + -2x + 2x Combine like terms: 25 + -25 = 0 -25 + -2X + 2x + xX = 0 + -2x + 2x -25 + -2X + 2x + xX = -2x + 2x Combine like terms: -2x + 2x = 0 -25 + -2X + 2x + xX = 0 The solution to this equation could not be determined.
