Simplifying (2x + 3)(2x + -3) = 9X Reorder the terms: (3 + 2x)(2x + -3) = 9X Reorder the terms: (3 + 2x)(-3 + 2x) = 9X Multiply (3 + 2x) * (-3 + 2x) (3(-3 + 2x) + 2x * (-3 + 2x)) = 9X ((-3 * 3 + 2x * 3) + 2x * (-3 + 2x)) = 9X ((-9 + 6x) + 2x * (-3 + 2x)) = 9X (-9 + 6x + (-3 * 2x + 2x * 2x)) = 9X (-9 + 6x + (-6x + 4x2)) = 9X Combine like terms: 6x + -6x = 0 (-9 + 0 + 4x2) = 9X (-9 + 4x2) = 9X Solving -9 + 4x2 = 9X Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + 4x2 = 9 + 9X Combine like terms: -9 + 9 = 0 0 + 4x2 = 9 + 9X 4x2 = 9 + 9X Divide each side by '4'. x2 = 2.25 + 2.25X Simplifying x2 = 2.25 + 2.25X Reorder the terms: -2.25 + -2.25X + x2 = 2.25 + 2.25X + -2.25 + -2.25X Reorder the terms: -2.25 + -2.25X + x2 = 2.25 + -2.25 + 2.25X + -2.25X Combine like terms: 2.25 + -2.25 = 0.00 -2.25 + -2.25X + x2 = 0.00 + 2.25X + -2.25X -2.25 + -2.25X + x2 = 2.25X + -2.25X Combine like terms: 2.25X + -2.25X = 0.00 -2.25 + -2.25X + x2 = 0.00 The solution to this equation could not be determined.
