Simplifying x2 + 2x + 1 + 4x + -64 = 0 Reorder the terms: 1 + -64 + 2x + 4x + x2 = 0 Combine like terms: 1 + -64 = -63 -63 + 2x + 4x + x2 = 0 Combine like terms: 2x + 4x = 6x -63 + 6x + x2 = 0 Solving -63 + 6x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '63' to each side of the equation. -63 + 6x + 63 + x2 = 0 + 63 Reorder the terms: -63 + 63 + 6x + x2 = 0 + 63 Combine like terms: -63 + 63 = 0 0 + 6x + x2 = 0 + 63 6x + x2 = 0 + 63 Combine like terms: 0 + 63 = 63 6x + x2 = 63 The x term is 6x. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6x + 9 + x2 = 63 + 9 Reorder the terms: 9 + 6x + x2 = 63 + 9 Combine like terms: 63 + 9 = 72 9 + 6x + x2 = 72 Factor a perfect square on the left side: (x + 3)(x + 3) = 72 Calculate the square root of the right side: 8.485281374 Break this problem into two subproblems by setting (x + 3) equal to 8.485281374 and -8.485281374.Subproblem 1
x + 3 = 8.485281374 Simplifying x + 3 = 8.485281374 Reorder the terms: 3 + x = 8.485281374 Solving 3 + x = 8.485281374 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = 8.485281374 + -3 Combine like terms: 3 + -3 = 0 0 + x = 8.485281374 + -3 x = 8.485281374 + -3 Combine like terms: 8.485281374 + -3 = 5.485281374 x = 5.485281374 Simplifying x = 5.485281374Subproblem 2
x + 3 = -8.485281374 Simplifying x + 3 = -8.485281374 Reorder the terms: 3 + x = -8.485281374 Solving 3 + x = -8.485281374 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = -8.485281374 + -3 Combine like terms: 3 + -3 = 0 0 + x = -8.485281374 + -3 x = -8.485281374 + -3 Combine like terms: -8.485281374 + -3 = -11.485281374 x = -11.485281374 Simplifying x = -11.485281374Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.485281374, -11.485281374}
