Simplifying x + 3 = x2 + -6x + 12 Reorder the terms: 3 + x = x2 + -6x + 12 Reorder the terms: 3 + x = 12 + -6x + x2 Solving 3 + x = 12 + -6x + x2 Solving for variable 'x'. Reorder the terms: 3 + -12 + x + 6x + -1x2 = 12 + -6x + x2 + -12 + 6x + -1x2 Combine like terms: 3 + -12 = -9 -9 + x + 6x + -1x2 = 12 + -6x + x2 + -12 + 6x + -1x2 Combine like terms: x + 6x = 7x -9 + 7x + -1x2 = 12 + -6x + x2 + -12 + 6x + -1x2 Reorder the terms: -9 + 7x + -1x2 = 12 + -12 + -6x + 6x + x2 + -1x2 Combine like terms: 12 + -12 = 0 -9 + 7x + -1x2 = 0 + -6x + 6x + x2 + -1x2 -9 + 7x + -1x2 = -6x + 6x + x2 + -1x2 Combine like terms: -6x + 6x = 0 -9 + 7x + -1x2 = 0 + x2 + -1x2 -9 + 7x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -9 + 7x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 9 + -7x + x2 = 0 Move the constant term to the right: Add '-9' to each side of the equation. 9 + -7x + -9 + x2 = 0 + -9 Reorder the terms: 9 + -9 + -7x + x2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -7x + x2 = 0 + -9 -7x + x2 = 0 + -9 Combine like terms: 0 + -9 = -9 -7x + x2 = -9 The x term is -7x. Take half its coefficient (-3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. -7x + 12.25 + x2 = -9 + 12.25 Reorder the terms: 12.25 + -7x + x2 = -9 + 12.25 Combine like terms: -9 + 12.25 = 3.25 12.25 + -7x + x2 = 3.25 Factor a perfect square on the left side: (x + -3.5)(x + -3.5) = 3.25 Calculate the square root of the right side: 1.802775638 Break this problem into two subproblems by setting (x + -3.5) equal to 1.802775638 and -1.802775638.Subproblem 1
x + -3.5 = 1.802775638 Simplifying x + -3.5 = 1.802775638 Reorder the terms: -3.5 + x = 1.802775638 Solving -3.5 + x = 1.802775638 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + x = 1.802775638 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + x = 1.802775638 + 3.5 x = 1.802775638 + 3.5 Combine like terms: 1.802775638 + 3.5 = 5.302775638 x = 5.302775638 Simplifying x = 5.302775638Subproblem 2
x + -3.5 = -1.802775638 Simplifying x + -3.5 = -1.802775638 Reorder the terms: -3.5 + x = -1.802775638 Solving -3.5 + x = -1.802775638 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + x = -1.802775638 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + x = -1.802775638 + 3.5 x = -1.802775638 + 3.5 Combine like terms: -1.802775638 + 3.5 = 1.697224362 x = 1.697224362 Simplifying x = 1.697224362Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.302775638, 1.697224362}
