Simplifying 7x = x2 + 12 + -3x Reorder the terms: 7x = 12 + -3x + x2 Solving 7x = 12 + -3x + x2 Solving for variable 'x'. Reorder the terms: -12 + 7x + 3x + -1x2 = 12 + -3x + x2 + -12 + 3x + -1x2 Combine like terms: 7x + 3x = 10x -12 + 10x + -1x2 = 12 + -3x + x2 + -12 + 3x + -1x2 Reorder the terms: -12 + 10x + -1x2 = 12 + -12 + -3x + 3x + x2 + -1x2 Combine like terms: 12 + -12 = 0 -12 + 10x + -1x2 = 0 + -3x + 3x + x2 + -1x2 -12 + 10x + -1x2 = -3x + 3x + x2 + -1x2 Combine like terms: -3x + 3x = 0 -12 + 10x + -1x2 = 0 + x2 + -1x2 -12 + 10x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -12 + 10x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 12 + -10x + x2 = 0 Move the constant term to the right: Add '-12' to each side of the equation. 12 + -10x + -12 + x2 = 0 + -12 Reorder the terms: 12 + -12 + -10x + x2 = 0 + -12 Combine like terms: 12 + -12 = 0 0 + -10x + x2 = 0 + -12 -10x + x2 = 0 + -12 Combine like terms: 0 + -12 = -12 -10x + x2 = -12 The x term is -10x. Take half its coefficient (-5). Square it (25) and add it to both sides. Add '25' to each side of the equation. -10x + 25 + x2 = -12 + 25 Reorder the terms: 25 + -10x + x2 = -12 + 25 Combine like terms: -12 + 25 = 13 25 + -10x + x2 = 13 Factor a perfect square on the left side: (x + -5)(x + -5) = 13 Calculate the square root of the right side: 3.605551275 Break this problem into two subproblems by setting (x + -5) equal to 3.605551275 and -3.605551275.Subproblem 1
x + -5 = 3.605551275 Simplifying x + -5 = 3.605551275 Reorder the terms: -5 + x = 3.605551275 Solving -5 + x = 3.605551275 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + x = 3.605551275 + 5 Combine like terms: -5 + 5 = 0 0 + x = 3.605551275 + 5 x = 3.605551275 + 5 Combine like terms: 3.605551275 + 5 = 8.605551275 x = 8.605551275 Simplifying x = 8.605551275Subproblem 2
x + -5 = -3.605551275 Simplifying x + -5 = -3.605551275 Reorder the terms: -5 + x = -3.605551275 Solving -5 + x = -3.605551275 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + x = -3.605551275 + 5 Combine like terms: -5 + 5 = 0 0 + x = -3.605551275 + 5 x = -3.605551275 + 5 Combine like terms: -3.605551275 + 5 = 1.394448725 x = 1.394448725 Simplifying x = 1.394448725Solution
