Simplifying 146 = x2 + 7x Reorder the terms: 146 = 7x + x2 Solving 146 = 7x + x2 Solving for variable 'x'. Reorder the terms: 146 + -7x + -1x2 = 7x + -7x + x2 + -1x2 Combine like terms: 7x + -7x = 0 146 + -7x + -1x2 = 0 + x2 + -1x2 146 + -7x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 146 + -7x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -146 + 7x + x2 = 0 Move the constant term to the right: Add '146' to each side of the equation. -146 + 7x + 146 + x2 = 0 + 146 Reorder the terms: -146 + 146 + 7x + x2 = 0 + 146 Combine like terms: -146 + 146 = 0 0 + 7x + x2 = 0 + 146 7x + x2 = 0 + 146 Combine like terms: 0 + 146 = 146 7x + x2 = 146 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 = 146 + 12.25 Reorder the terms: 12.25 + 7x + x2 = 146 + 12.25 Combine like terms: 146 + 12.25 = 158.25 12.25 + 7x + x2 = 158.25 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 158.25 Calculate the square root of the right side: 12.579745625 Break this problem into two subproblems by setting (x + 3.5) equal to 12.579745625 and -12.579745625.Subproblem 1
x + 3.5 = 12.579745625 Simplifying x + 3.5 = 12.579745625 Reorder the terms: 3.5 + x = 12.579745625 Solving 3.5 + x = 12.579745625 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 = 12.579745625 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = 12.579745625 + -3.5 x = 12.579745625 + -3.5 Combine like terms: 12.579745625 + -3.5 = 9.079745625 x = 9.079745625 Simplifying x = 9.079745625Subproblem 2
x + 3.5 = -12.579745625 Simplifying x + 3.5 = -12.579745625 Reorder the terms: 3.5 + x = -12.579745625 Solving 3.5 + x = -12.579745625 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 = -12.579745625 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = -12.579745625 + -3.5 x = -12.579745625 + -3.5 Combine like terms: -12.579745625 + -3.5 = -16.079745625 x = -16.079745625 Simplifying x = -16.079745625Solution
