Simplifying 64 = x(x + 14) Reorder the terms: 64 = x(14 + x) 64 = (14 * x + x * x) 64 = (14x + x2) Solving 64 = 14x + x2 Solving for variable 'x'. Reorder the terms: 64 + -14x + -1x2 = 14x + -14x + x2 + -1x2 Combine like terms: 14x + -14x = 0 64 + -14x + -1x2 = 0 + x2 + -1x2 64 + -14x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 64 + -14x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -64 + 14x + x2 = 0 Move the constant term to the right: Add '64' to each side of the equation. -64 + 14x + 64 + x2 = 0 + 64 Reorder the terms: -64 + 64 + 14x + x2 = 0 + 64 Combine like terms: -64 + 64 = 0 0 + 14x + x2 = 0 + 64 14x + x2 = 0 + 64 Combine like terms: 0 + 64 = 64 14x + x2 = 64 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 = 64 + 49 Reorder the terms: 49 + 14x + x2 = 64 + 49 Combine like terms: 64 + 49 = 113 49 + 14x + x2 = 113 Factor a perfect square on the left side: (x + 7)(x + 7) = 113 Calculate the square root of the right side: 10.630145813 Break this problem into two subproblems by setting (x + 7) equal to 10.630145813 and -10.630145813.Subproblem 1
x + 7 = 10.630145813 Simplifying x + 7 = 10.630145813 Reorder the terms: 7 + x = 10.630145813 Solving 7 + x = 10.630145813 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 = 10.630145813 + -7 Combine like terms: 7 + -7 = 0 0 + x = 10.630145813 + -7 x = 10.630145813 + -7 Combine like terms: 10.630145813 + -7 = 3.630145813 x = 3.630145813 Simplifying x = 3.630145813Subproblem 2
x + 7 = -10.630145813 Simplifying x + 7 = -10.630145813 Reorder the terms: 7 + x = -10.630145813 Solving 7 + x = -10.630145813 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 = -10.630145813 + -7 Combine like terms: 7 + -7 = 0 0 + x = -10.630145813 + -7 x = -10.630145813 + -7 Combine like terms: -10.630145813 + -7 = -17.630145813 x = -17.630145813 Simplifying x = -17.630145813Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.630145813, -17.630145813}
