Simplifying 2x(x + 4) = 1 Reorder the terms: 2x(4 + x) = 1 (4 * 2x + x * 2x) = 1 (8x + 2x2) = 1 Solving 8x + 2x2 = 1 Solving for variable 'x'. Reorder the terms: -1 + 8x + 2x2 = 1 + -1 Combine like terms: 1 + -1 = 0 -1 + 8x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -0.5 + 4x + x2 = 0 Move the constant term to the right: Add '0.5' to each side of the equation. -0.5 + 4x + 0.5 + x2 = 0 + 0.5 Reorder the terms: -0.5 + 0.5 + 4x + x2 = 0 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + 4x + x2 = 0 + 0.5 4x + x2 = 0 + 0.5 Combine like terms: 0 + 0.5 = 0.5 4x + x2 = 0.5 The x term is 4x. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4x + 4 + x2 = 0.5 + 4 Reorder the terms: 4 + 4x + x2 = 0.5 + 4 Combine like terms: 0.5 + 4 = 4.5 4 + 4x + x2 = 4.5 Factor a perfect square on the left side: (x + 2)(x + 2) = 4.5 Calculate the square root of the right side: 2.121320344 Break this problem into two subproblems by setting (x + 2) equal to 2.121320344 and -2.121320344.Subproblem 1
x + 2 = 2.121320344 Simplifying x + 2 = 2.121320344 Reorder the terms: 2 + x = 2.121320344 Solving 2 + x = 2.121320344 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 2.121320344 + -2 Combine like terms: 2 + -2 = 0 0 + x = 2.121320344 + -2 x = 2.121320344 + -2 Combine like terms: 2.121320344 + -2 = 0.121320344 x = 0.121320344 Simplifying x = 0.121320344Subproblem 2
x + 2 = -2.121320344 Simplifying x + 2 = -2.121320344 Reorder the terms: 2 + x = -2.121320344 Solving 2 + x = -2.121320344 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = -2.121320344 + -2 Combine like terms: 2 + -2 = 0 0 + x = -2.121320344 + -2 x = -2.121320344 + -2 Combine like terms: -2.121320344 + -2 = -4.121320344 x = -4.121320344 Simplifying x = -4.121320344Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.121320344, -4.121320344}
