Simplifying 12 = 6x + x2 Solving 12 = 6x + x2 Solving for variable 'x'. Reorder the terms: 12 + -6x + -1x2 = 6x + -6x + x2 + -1x2 Combine like terms: 6x + -6x = 0 12 + -6x + -1x2 = 0 + x2 + -1x2 12 + -6x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 12 + -6x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -12 + 6x + x2 = 0 Move the constant term to the right: Add '12' to each side of the equation. -12 + 6x + 12 + x2 = 0 + 12 Reorder the terms: -12 + 12 + 6x + x2 = 0 + 12 Combine like terms: -12 + 12 = 0 0 + 6x + x2 = 0 + 12 6x + x2 = 0 + 12 Combine like terms: 0 + 12 = 12 6x + x2 = 12 The x term is 6x. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6x + 9 + x2 = 12 + 9 Reorder the terms: 9 + 6x + x2 = 12 + 9 Combine like terms: 12 + 9 = 21 9 + 6x + x2 = 21 Factor a perfect square on the left side: (x + 3)(x + 3) = 21 Calculate the square root of the right side: 4.582575695 Break this problem into two subproblems by setting (x + 3) equal to 4.582575695 and -4.582575695.Subproblem 1
x + 3 = 4.582575695 Simplifying x + 3 = 4.582575695 Reorder the terms: 3 + x = 4.582575695 Solving 3 + x = 4.582575695 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = 4.582575695 + -3 Combine like terms: 3 + -3 = 0 0 + x = 4.582575695 + -3 x = 4.582575695 + -3 Combine like terms: 4.582575695 + -3 = 1.582575695 x = 1.582575695 Simplifying x = 1.582575695Subproblem 2
x + 3 = -4.582575695 Simplifying x + 3 = -4.582575695 Reorder the terms: 3 + x = -4.582575695 Solving 3 + x = -4.582575695 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = -4.582575695 + -3 Combine like terms: 3 + -3 = 0 0 + x = -4.582575695 + -3 x = -4.582575695 + -3 Combine like terms: -4.582575695 + -3 = -7.582575695 x = -7.582575695 Simplifying x = -7.582575695Solution
