Simplifying 8x2 + 16x + -13 = 0 Reorder the terms: -13 + 16x + 8x2 = 0 Solving -13 + 16x + 8x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -1.625 + 2x + x2 = 0 Move the constant term to the right: Add '1.625' to each side of the equation. -1.625 + 2x + 1.625 + x2 = 0 + 1.625 Reorder the terms: -1.625 + 1.625 + 2x + x2 = 0 + 1.625 Combine like terms: -1.625 + 1.625 = 0.000 0.000 + 2x + x2 = 0 + 1.625 2x + x2 = 0 + 1.625 Combine like terms: 0 + 1.625 = 1.625 2x + x2 = 1.625 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 1.625 + 1 Reorder the terms: 1 + 2x + x2 = 1.625 + 1 Combine like terms: 1.625 + 1 = 2.625 1 + 2x + x2 = 2.625 Factor a perfect square on the left side: (x + 1)(x + 1) = 2.625 Calculate the square root of the right side: 1.620185175 Break this problem into two subproblems by setting (x + 1) equal to 1.620185175 and -1.620185175.Subproblem 1
x + 1 = 1.620185175 Simplifying x + 1 = 1.620185175 Reorder the terms: 1 + x = 1.620185175 Solving 1 + x = 1.620185175 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 1.620185175 + -1 Combine like terms: 1 + -1 = 0 0 + x = 1.620185175 + -1 x = 1.620185175 + -1 Combine like terms: 1.620185175 + -1 = 0.620185175 x = 0.620185175 Simplifying x = 0.620185175Subproblem 2
x + 1 = -1.620185175 Simplifying x + 1 = -1.620185175 Reorder the terms: 1 + x = -1.620185175 Solving 1 + x = -1.620185175 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = -1.620185175 + -1 Combine like terms: 1 + -1 = 0 0 + x = -1.620185175 + -1 x = -1.620185175 + -1 Combine like terms: -1.620185175 + -1 = -2.620185175 x = -2.620185175 Simplifying x = -2.620185175Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.620185175, -2.620185175}
