Simplifying (x + -3)(x + 3) = x2 + 18x Reorder the terms: (-3 + x)(x + 3) = x2 + 18x Reorder the terms: (-3 + x)(3 + x) = x2 + 18x Multiply (-3 + x) * (3 + x) (-3(3 + x) + x(3 + x)) = x2 + 18x ((3 * -3 + x * -3) + x(3 + x)) = x2 + 18x ((-9 + -3x) + x(3 + x)) = x2 + 18x (-9 + -3x + (3 * x + x * x)) = x2 + 18x (-9 + -3x + (3x + x2)) = x2 + 18x Combine like terms: -3x + 3x = 0 (-9 + 0 + x2) = x2 + 18x (-9 + x2) = x2 + 18x Reorder the terms: -9 + x2 = 18x + x2 Add '-1x2' to each side of the equation. -9 + x2 + -1x2 = 18x + x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -9 + 0 = 18x + x2 + -1x2 -9 = 18x + x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -9 = 18x + 0 -9 = 18x Solving -9 = 18x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-18x' to each side of the equation. -9 + -18x = 18x + -18x Combine like terms: 18x + -18x = 0 -9 + -18x = 0 Add '9' to each side of the equation. -9 + 9 + -18x = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -18x = 0 + 9 -18x = 0 + 9 Combine like terms: 0 + 9 = 9 -18x = 9 Divide each side by '-18'. x = -0.5 Simplifying x = -0.5
