Simplifying 3x(x) + 81 = (x + 3)(3x + 3) Multiply x * x 3x2 + 81 = (x + 3)(3x + 3) Reorder the terms: 81 + 3x2 = (x + 3)(3x + 3) Reorder the terms: 81 + 3x2 = (3 + x)(3x + 3) Reorder the terms: 81 + 3x2 = (3 + x)(3 + 3x) Multiply (3 + x) * (3 + 3x) 81 + 3x2 = (3(3 + 3x) + x(3 + 3x)) 81 + 3x2 = ((3 * 3 + 3x * 3) + x(3 + 3x)) 81 + 3x2 = ((9 + 9x) + x(3 + 3x)) 81 + 3x2 = (9 + 9x + (3 * x + 3x * x)) 81 + 3x2 = (9 + 9x + (3x + 3x2)) Combine like terms: 9x + 3x = 12x 81 + 3x2 = (9 + 12x + 3x2) Add '-3x2' to each side of the equation. 81 + 3x2 + -3x2 = 9 + 12x + 3x2 + -3x2 Combine like terms: 3x2 + -3x2 = 0 81 + 0 = 9 + 12x + 3x2 + -3x2 81 = 9 + 12x + 3x2 + -3x2 Combine like terms: 3x2 + -3x2 = 0 81 = 9 + 12x + 0 81 = 9 + 12x Solving 81 = 9 + 12x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-12x' to each side of the equation. 81 + -12x = 9 + 12x + -12x Combine like terms: 12x + -12x = 0 81 + -12x = 9 + 0 81 + -12x = 9 Add '-81' to each side of the equation. 81 + -81 + -12x = 9 + -81 Combine like terms: 81 + -81 = 0 0 + -12x = 9 + -81 -12x = 9 + -81 Combine like terms: 9 + -81 = -72 -12x = -72 Divide each side by '-12'. x = 6 Simplifying x = 6
