Simplifying x(4 + x) = 12(12 + 3) (4 * x + x * x) = 12(12 + 3) (4x + x2) = 12(12 + 3) Combine like terms: 12 + 3 = 15 4x + x2 = 12(15) Multiply 12 * 15 4x + x2 = 180 Solving 4x + x2 = 180 Solving for variable 'x'. Reorder the terms: -180 + 4x + x2 = 180 + -180 Combine like terms: 180 + -180 = 0 -180 + 4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '180' to each side of the equation. -180 + 4x + 180 + x2 = 0 + 180 Reorder the terms: -180 + 180 + 4x + x2 = 0 + 180 Combine like terms: -180 + 180 = 0 0 + 4x + x2 = 0 + 180 4x + x2 = 0 + 180 Combine like terms: 0 + 180 = 180 4x + x2 = 180 The x term is 4x. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4x + 4 + x2 = 180 + 4 Reorder the terms: 4 + 4x + x2 = 180 + 4 Combine like terms: 180 + 4 = 184 4 + 4x + x2 = 184 Factor a perfect square on the left side: (x + 2)(x + 2) = 184 Calculate the square root of the right side: 13.564659966 Break this problem into two subproblems by setting (x + 2) equal to 13.564659966 and -13.564659966.Subproblem 1
x + 2 = 13.564659966 Simplifying x + 2 = 13.564659966 Reorder the terms: 2 + x = 13.564659966 Solving 2 + x = 13.564659966 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 13.564659966 + -2 Combine like terms: 2 + -2 = 0 0 + x = 13.564659966 + -2 x = 13.564659966 + -2 Combine like terms: 13.564659966 + -2 = 11.564659966 x = 11.564659966 Simplifying x = 11.564659966Subproblem 2
x + 2 = -13.564659966 Simplifying x + 2 = -13.564659966 Reorder the terms: 2 + x = -13.564659966 Solving 2 + x = -13.564659966 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = -13.564659966 + -2 Combine like terms: 2 + -2 = 0 0 + x = -13.564659966 + -2 x = -13.564659966 + -2 Combine like terms: -13.564659966 + -2 = -15.564659966 x = -15.564659966 Simplifying x = -15.564659966Solution
