Simplifying x = 4x + x2 + -12 Reorder the terms: x = -12 + 4x + x2 Solving x = -12 + 4x + x2 Solving for variable 'x'. Reorder the terms: 12 + x + -4x + -1x2 = -12 + 4x + x2 + 12 + -4x + -1x2 Combine like terms: x + -4x = -3x 12 + -3x + -1x2 = -12 + 4x + x2 + 12 + -4x + -1x2 Reorder the terms: 12 + -3x + -1x2 = -12 + 12 + 4x + -4x + x2 + -1x2 Combine like terms: -12 + 12 = 0 12 + -3x + -1x2 = 0 + 4x + -4x + x2 + -1x2 12 + -3x + -1x2 = 4x + -4x + x2 + -1x2 Combine like terms: 4x + -4x = 0 12 + -3x + -1x2 = 0 + x2 + -1x2 12 + -3x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 12 + -3x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -12 + 3x + x2 = 0 Move the constant term to the right: Add '12' to each side of the equation. -12 + 3x + 12 + x2 = 0 + 12 Reorder the terms: -12 + 12 + 3x + x2 = 0 + 12 Combine like terms: -12 + 12 = 0 0 + 3x + x2 = 0 + 12 3x + x2 = 0 + 12 Combine like terms: 0 + 12 = 12 3x + x2 = 12 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 12 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 12 + 2.25 Combine like terms: 12 + 2.25 = 14.25 2.25 + 3x + x2 = 14.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 14.25 Calculate the square root of the right side: 3.774917218 Break this problem into two subproblems by setting (x + 1.5) equal to 3.774917218 and -3.774917218.Subproblem 1
x + 1.5 = 3.774917218 Simplifying x + 1.5 = 3.774917218 Reorder the terms: 1.5 + x = 3.774917218 Solving 1.5 + x = 3.774917218 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 3.774917218 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 3.774917218 + -1.5 x = 3.774917218 + -1.5 Combine like terms: 3.774917218 + -1.5 = 2.274917218 x = 2.274917218 Simplifying x = 2.274917218Subproblem 2
x + 1.5 = -3.774917218 Simplifying x + 1.5 = -3.774917218 Reorder the terms: 1.5 + x = -3.774917218 Solving 1.5 + x = -3.774917218 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -3.774917218 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -3.774917218 + -1.5 x = -3.774917218 + -1.5 Combine like terms: -3.774917218 + -1.5 = -5.274917218 x = -5.274917218 Simplifying x = -5.274917218Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.274917218, -5.274917218}
