Simplifying x2 + -1x + -45 = 7 Reorder the terms: -45 + -1x + x2 = 7 Solving -45 + -1x + x2 = 7 Solving for variable 'x'. Reorder the terms: -45 + -7 + -1x + x2 = 7 + -7 Combine like terms: -45 + -7 = -52 -52 + -1x + x2 = 7 + -7 Combine like terms: 7 + -7 = 0 -52 + -1x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '52' to each side of the equation. -52 + -1x + 52 + x2 = 0 + 52 Reorder the terms: -52 + 52 + -1x + x2 = 0 + 52 Combine like terms: -52 + 52 = 0 0 + -1x + x2 = 0 + 52 -1x + x2 = 0 + 52 Combine like terms: 0 + 52 = 52 -1x + x2 = 52 The x term is -1x. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = 52 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 52 + 0.25 Combine like terms: 52 + 0.25 = 52.25 0.25 + -1x + x2 = 52.25 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 52.25 Calculate the square root of the right side: 7.228416147 Break this problem into two subproblems by setting (x + -0.5) equal to 7.228416147 and -7.228416147.Subproblem 1
x + -0.5 = 7.228416147 Simplifying x + -0.5 = 7.228416147 Reorder the terms: -0.5 + x = 7.228416147 Solving -0.5 + x = 7.228416147 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = 7.228416147 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 7.228416147 + 0.5 x = 7.228416147 + 0.5 Combine like terms: 7.228416147 + 0.5 = 7.728416147 x = 7.728416147 Simplifying x = 7.728416147Subproblem 2
x + -0.5 = -7.228416147 Simplifying x + -0.5 = -7.228416147 Reorder the terms: -0.5 + x = -7.228416147 Solving -0.5 + x = -7.228416147 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = -7.228416147 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -7.228416147 + 0.5 x = -7.228416147 + 0.5 Combine like terms: -7.228416147 + 0.5 = -6.728416147 x = -6.728416147 Simplifying x = -6.728416147Solution
The solution to the problem is based on the solutions from the subproblems. x = {7.728416147, -6.728416147}
