Simplifying (X + -2)(x + 2) = 9 Reorder the terms: (-2 + X)(x + 2) = 9 Reorder the terms: (-2 + X)(2 + x) = 9 Multiply (-2 + X) * (2 + x) (-2(2 + x) + X(2 + x)) = 9 ((2 * -2 + x * -2) + X(2 + x)) = 9 ((-4 + -2x) + X(2 + x)) = 9 (-4 + -2x + (2 * X + x * X)) = 9 (-4 + -2x + (2X + xX)) = 9 Reorder the terms: (-4 + 2X + -2x + xX) = 9 (-4 + 2X + -2x + xX) = 9 Solving -4 + 2X + -2x + xX = 9 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 = 9 + 4 Reorder the terms: -4 + 4 + 2X + -2x + xX = 9 + 4 Combine like terms: -4 + 4 = 0 0 + 2X + -2x + xX = 9 + 4 2X + -2x + xX = 9 + 4 Combine like terms: 9 + 4 = 13 2X + -2x + xX = 13 Add '2x' to each side of the equation. 2X + -2x + 2x + xX = 13 + 2x Combine like terms: -2x + 2x = 0 2X + 0 + xX = 13 + 2x 2X + xX = 13 + 2x Reorder the terms: -13 + 2X + -2x + xX = 13 + 2x + -13 + -2x Reorder the terms: -13 + 2X + -2x + xX = 13 + -13 + 2x + -2x Combine like terms: 13 + -13 = 0 -13 + 2X + -2x + xX = 0 + 2x + -2x -13 + 2X + -2x + xX = 2x + -2x Combine like terms: 2x + -2x = 0 -13 + 2X + -2x + xX = 0 The solution to this equation could not be determined.
