Simplifying 7x + 100 = x2 + -90 Reorder the terms: 100 + 7x = x2 + -90 Reorder the terms: 100 + 7x = -90 + x2 Solving 100 + 7x = -90 + x2 Solving for variable 'x'. Reorder the terms: 100 + 90 + 7x + -1x2 = -90 + x2 + 90 + -1x2 Combine like terms: 100 + 90 = 190 190 + 7x + -1x2 = -90 + x2 + 90 + -1x2 Reorder the terms: 190 + 7x + -1x2 = -90 + 90 + x2 + -1x2 Combine like terms: -90 + 90 = 0 190 + 7x + -1x2 = 0 + x2 + -1x2 190 + 7x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 190 + 7x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -190 + -7x + x2 = 0 Move the constant term to the right: Add '190' to each side of the equation. -190 + -7x + 190 + x2 = 0 + 190 Reorder the terms: -190 + 190 + -7x + x2 = 0 + 190 Combine like terms: -190 + 190 = 0 0 + -7x + x2 = 0 + 190 -7x + x2 = 0 + 190 Combine like terms: 0 + 190 = 190 -7x + x2 = 190 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 = 190 + 12.25 Reorder the terms: 12.25 + -7x + x2 = 190 + 12.25 Combine like terms: 190 + 12.25 = 202.25 12.25 + -7x + x2 = 202.25 Factor a perfect square on the left side: (x + -3.5)(x + -3.5) = 202.25 Calculate the square root of the right side: 14.221462653 Break this problem into two subproblems by setting (x + -3.5) equal to 14.221462653 and -14.221462653.Subproblem 1
x + -3.5 = 14.221462653 Simplifying x + -3.5 = 14.221462653 Reorder the terms: -3.5 + x = 14.221462653 Solving -3.5 + x = 14.221462653 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 = 14.221462653 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + x = 14.221462653 + 3.5 x = 14.221462653 + 3.5 Combine like terms: 14.221462653 + 3.5 = 17.721462653 x = 17.721462653 Simplifying x = 17.721462653Subproblem 2
x + -3.5 = -14.221462653 Simplifying x + -3.5 = -14.221462653 Reorder the terms: -3.5 + x = -14.221462653 Solving -3.5 + x = -14.221462653 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 = -14.221462653 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + x = -14.221462653 + 3.5 x = -14.221462653 + 3.5 Combine like terms: -14.221462653 + 3.5 = -10.721462653 x = -10.721462653 Simplifying x = -10.721462653Solution
