Simplifying x2 + -14x = -9 Reorder the terms: -14x + x2 = -9 Solving -14x + x2 = -9 Solving for variable 'x'. Reorder the terms: 9 + -14x + x2 = -9 + 9 Combine like terms: -9 + 9 = 0 9 + -14x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-9' to each side of the equation. 9 + -14x + -9 + x2 = 0 + -9 Reorder the terms: 9 + -9 + -14x + x2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -14x + x2 = 0 + -9 -14x + x2 = 0 + -9 Combine like terms: 0 + -9 = -9 -14x + x2 = -9 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 = -9 + 49 Reorder the terms: 49 + -14x + x2 = -9 + 49 Combine like terms: -9 + 49 = 40 49 + -14x + x2 = 40 Factor a perfect square on the left side: (x + -7)(x + -7) = 40 Calculate the square root of the right side: 6.32455532 Break this problem into two subproblems by setting (x + -7) equal to 6.32455532 and -6.32455532.Subproblem 1
x + -7 = 6.32455532 Simplifying x + -7 = 6.32455532 Reorder the terms: -7 + x = 6.32455532 Solving -7 + x = 6.32455532 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 = 6.32455532 + 7 Combine like terms: -7 + 7 = 0 0 + x = 6.32455532 + 7 x = 6.32455532 + 7 Combine like terms: 6.32455532 + 7 = 13.32455532 x = 13.32455532 Simplifying x = 13.32455532Subproblem 2
x + -7 = -6.32455532 Simplifying x + -7 = -6.32455532 Reorder the terms: -7 + x = -6.32455532 Solving -7 + x = -6.32455532 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 = -6.32455532 + 7 Combine like terms: -7 + 7 = 0 0 + x = -6.32455532 + 7 x = -6.32455532 + 7 Combine like terms: -6.32455532 + 7 = 0.67544468 x = 0.67544468 Simplifying x = 0.67544468Solution
