Simplifying (x + -3)(x + 3) + -1x(x + -4) = 1 Reorder the terms: (-3 + x)(x + 3) + -1x(x + -4) = 1 Reorder the terms: (-3 + x)(3 + x) + -1x(x + -4) = 1 Multiply (-3 + x) * (3 + x) (-3(3 + x) + x(3 + x)) + -1x(x + -4) = 1 ((3 * -3 + x * -3) + x(3 + x)) + -1x(x + -4) = 1 ((-9 + -3x) + x(3 + x)) + -1x(x + -4) = 1 (-9 + -3x + (3 * x + x * x)) + -1x(x + -4) = 1 (-9 + -3x + (3x + x2)) + -1x(x + -4) = 1 Combine like terms: -3x + 3x = 0 (-9 + 0 + x2) + -1x(x + -4) = 1 (-9 + x2) + -1x(x + -4) = 1 Reorder the terms: -9 + x2 + -1x(-4 + x) = 1 -9 + x2 + (-4 * -1x + x * -1x) = 1 -9 + x2 + (4x + -1x2) = 1 Reorder the terms: -9 + 4x + x2 + -1x2 = 1 Combine like terms: x2 + -1x2 = 0 -9 + 4x + 0 = 1 -9 + 4x = 1 Solving -9 + 4x = 1 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 + 4x = 1 + 9 Combine like terms: -9 + 9 = 0 0 + 4x = 1 + 9 4x = 1 + 9 Combine like terms: 1 + 9 = 10 4x = 10 Divide each side by '4'. x = 2.5 Simplifying x = 2.5
