Simplifying x2 + 7x + 13 = 180 Reorder the terms: 13 + 7x + x2 = 180 Solving 13 + 7x + x2 = 180 Solving for variable 'x'. Reorder the terms: 13 + -180 + 7x + x2 = 180 + -180 Combine like terms: 13 + -180 = -167 -167 + 7x + x2 = 180 + -180 Combine like terms: 180 + -180 = 0 -167 + 7x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '167' to each side of the equation. -167 + 7x + 167 + x2 = 0 + 167 Reorder the terms: -167 + 167 + 7x + x2 = 0 + 167 Combine like terms: -167 + 167 = 0 0 + 7x + x2 = 0 + 167 7x + x2 = 0 + 167 Combine like terms: 0 + 167 = 167 7x + x2 = 167 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 = 167 + 12.25 Reorder the terms: 12.25 + 7x + x2 = 167 + 12.25 Combine like terms: 167 + 12.25 = 179.25 12.25 + 7x + x2 = 179.25 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 179.25 Calculate the square root of the right side: 13.388427839 Break this problem into two subproblems by setting (x + 3.5) equal to 13.388427839 and -13.388427839.Subproblem 1
x + 3.5 = 13.388427839 Simplifying x + 3.5 = 13.388427839 Reorder the terms: 3.5 + x = 13.388427839 Solving 3.5 + x = 13.388427839 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 = 13.388427839 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = 13.388427839 + -3.5 x = 13.388427839 + -3.5 Combine like terms: 13.388427839 + -3.5 = 9.888427839 x = 9.888427839 Simplifying x = 9.888427839Subproblem 2
x + 3.5 = -13.388427839 Simplifying x + 3.5 = -13.388427839 Reorder the terms: 3.5 + x = -13.388427839 Solving 3.5 + x = -13.388427839 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 = -13.388427839 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = -13.388427839 + -3.5 x = -13.388427839 + -3.5 Combine like terms: -13.388427839 + -3.5 = -16.888427839 x = -16.888427839 Simplifying x = -16.888427839Solution
The solution to the problem is based on the solutions from the subproblems. x = {9.888427839, -16.888427839}
