Simplifying 5x(2x + -1) + 5 = 13 Reorder the terms: 5x(-1 + 2x) + 5 = 13 (-1 * 5x + 2x * 5x) + 5 = 13 (-5x + 10x2) + 5 = 13 Reorder the terms: 5 + -5x + 10x2 = 13 Solving 5 + -5x + 10x2 = 13 Solving for variable 'x'. Reorder the terms: 5 + -13 + -5x + 10x2 = 13 + -13 Combine like terms: 5 + -13 = -8 -8 + -5x + 10x2 = 13 + -13 Combine like terms: 13 + -13 = 0 -8 + -5x + 10x2 = 0 Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. -0.8 + -0.5x + x2 = 0.0 Move the constant term to the right: Add '0.8' to each side of the equation. -0.8 + -0.5x + 0.8 + x2 = 0.0 + 0.8 Reorder the terms: -0.8 + 0.8 + -0.5x + x2 = 0.0 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + -0.5x + x2 = 0.0 + 0.8 -0.5x + x2 = 0.0 + 0.8 Combine like terms: 0.0 + 0.8 = 0.8 -0.5x + x2 = 0.8 The x term is -0.5x. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5x + 0.0625 + x2 = 0.8 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = 0.8 + 0.0625 Combine like terms: 0.8 + 0.0625 = 0.8625 0.0625 + -0.5x + x2 = 0.8625 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = 0.8625 Calculate the square root of the right side: 0.928708781 Break this problem into two subproblems by setting (x + -0.25) equal to 0.928708781 and -0.928708781.Subproblem 1
x + -0.25 = 0.928708781 Simplifying x + -0.25 = 0.928708781 Reorder the terms: -0.25 + x = 0.928708781 Solving -0.25 + x = 0.928708781 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = 0.928708781 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = 0.928708781 + 0.25 x = 0.928708781 + 0.25 Combine like terms: 0.928708781 + 0.25 = 1.178708781 x = 1.178708781 Simplifying x = 1.178708781Subproblem 2
x + -0.25 = -0.928708781 Simplifying x + -0.25 = -0.928708781 Reorder the terms: -0.25 + x = -0.928708781 Solving -0.25 + x = -0.928708781 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = -0.928708781 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = -0.928708781 + 0.25 x = -0.928708781 + 0.25 Combine like terms: -0.928708781 + 0.25 = -0.678708781 x = -0.678708781 Simplifying x = -0.678708781Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.178708781, -0.678708781}
