Simplifying x2 + -14x + -40 = 0 Reorder the terms: -40 + -14x + x2 = 0 Solving -40 + -14x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '40' to each side of the equation. -40 + -14x + 40 + x2 = 0 + 40 Reorder the terms: -40 + 40 + -14x + x2 = 0 + 40 Combine like terms: -40 + 40 = 0 0 + -14x + x2 = 0 + 40 -14x + x2 = 0 + 40 Combine like terms: 0 + 40 = 40 -14x + x2 = 40 The x term is -14x. Take half its coefficient (-7). Square it (49) and add it to both sides. Add '49' to each side of the equation. -14x + 49 + x2 = 40 + 49 Reorder the terms: 49 + -14x + x2 = 40 + 49 Combine like terms: 40 + 49 = 89 49 + -14x + x2 = 89 Factor a perfect square on the left side: (x + -7)(x + -7) = 89 Calculate the square root of the right side: 9.433981132 Break this problem into two subproblems by setting (x + -7) equal to 9.433981132 and -9.433981132.Subproblem 1
x + -7 = 9.433981132 Simplifying x + -7 = 9.433981132 Reorder the terms: -7 + x = 9.433981132 Solving -7 + x = 9.433981132 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + x = 9.433981132 + 7 Combine like terms: -7 + 7 = 0 0 + x = 9.433981132 + 7 x = 9.433981132 + 7 Combine like terms: 9.433981132 + 7 = 16.433981132 x = 16.433981132 Simplifying x = 16.433981132Subproblem 2
x + -7 = -9.433981132 Simplifying x + -7 = -9.433981132 Reorder the terms: -7 + x = -9.433981132 Solving -7 + x = -9.433981132 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + x = -9.433981132 + 7 Combine like terms: -7 + 7 = 0 0 + x = -9.433981132 + 7 x = -9.433981132 + 7 Combine like terms: -9.433981132 + 7 = -2.433981132 x = -2.433981132 Simplifying x = -2.433981132Solution
The solution to the problem is based on the solutions from the subproblems. x = {16.433981132, -2.433981132}
