Simplifying -1x2 + -64x + 16 = 0 Reorder the terms: 16 + -64x + -1x2 = 0 Solving 16 + -64x + -1x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -16 + 64x + x2 = 0 Move the constant term to the right: Add '16' to each side of the equation. -16 + 64x + 16 + x2 = 0 + 16 Reorder the terms: -16 + 16 + 64x + x2 = 0 + 16 Combine like terms: -16 + 16 = 0 0 + 64x + x2 = 0 + 16 64x + x2 = 0 + 16 Combine like terms: 0 + 16 = 16 64x + x2 = 16 The x term is 64x. Take half its coefficient (32). Square it (1024) and add it to both sides. Add '1024' to each side of the equation. 64x + 1024 + x2 = 16 + 1024 Reorder the terms: 1024 + 64x + x2 = 16 + 1024 Combine like terms: 16 + 1024 = 1040 1024 + 64x + x2 = 1040 Factor a perfect square on the left side: (x + 32)(x + 32) = 1040 Calculate the square root of the right side: 32.249030993 Break this problem into two subproblems by setting (x + 32) equal to 32.249030993 and -32.249030993.Subproblem 1
x + 32 = 32.249030993 Simplifying x + 32 = 32.249030993 Reorder the terms: 32 + x = 32.249030993 Solving 32 + x = 32.249030993 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-32' to each side of the equation. 32 + -32 + x = 32.249030993 + -32 Combine like terms: 32 + -32 = 0 0 + x = 32.249030993 + -32 x = 32.249030993 + -32 Combine like terms: 32.249030993 + -32 = 0.249030993 x = 0.249030993 Simplifying x = 0.249030993Subproblem 2
x + 32 = -32.249030993 Simplifying x + 32 = -32.249030993 Reorder the terms: 32 + x = -32.249030993 Solving 32 + x = -32.249030993 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-32' to each side of the equation. 32 + -32 + x = -32.249030993 + -32 Combine like terms: 32 + -32 = 0 0 + x = -32.249030993 + -32 x = -32.249030993 + -32 Combine like terms: -32.249030993 + -32 = -64.249030993 x = -64.249030993 Simplifying x = -64.249030993Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.249030993, -64.249030993}
