Simplifying 16x2 + 40x + 5 = 0 Reorder the terms: 5 + 40x + 16x2 = 0 Solving 5 + 40x + 16x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. 0.3125 + 2.5x + x2 = 0 Move the constant term to the right: Add '-0.3125' to each side of the equation. 0.3125 + 2.5x + -0.3125 + x2 = 0 + -0.3125 Reorder the terms: 0.3125 + -0.3125 + 2.5x + x2 = 0 + -0.3125 Combine like terms: 0.3125 + -0.3125 = 0.0000 0.0000 + 2.5x + x2 = 0 + -0.3125 2.5x + x2 = 0 + -0.3125 Combine like terms: 0 + -0.3125 = -0.3125 2.5x + x2 = -0.3125 The x term is 2.5x. Take half its coefficient (1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. 2.5x + 1.5625 + x2 = -0.3125 + 1.5625 Reorder the terms: 1.5625 + 2.5x + x2 = -0.3125 + 1.5625 Combine like terms: -0.3125 + 1.5625 = 1.25 1.5625 + 2.5x + x2 = 1.25 Factor a perfect square on the left side: (x + 1.25)(x + 1.25) = 1.25 Calculate the square root of the right side: 1.118033989 Break this problem into two subproblems by setting (x + 1.25) equal to 1.118033989 and -1.118033989.Subproblem 1
x + 1.25 = 1.118033989 Simplifying x + 1.25 = 1.118033989 Reorder the terms: 1.25 + x = 1.118033989 Solving 1.25 + x = 1.118033989 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = 1.118033989 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = 1.118033989 + -1.25 x = 1.118033989 + -1.25 Combine like terms: 1.118033989 + -1.25 = -0.131966011 x = -0.131966011 Simplifying x = -0.131966011Subproblem 2
x + 1.25 = -1.118033989 Simplifying x + 1.25 = -1.118033989 Reorder the terms: 1.25 + x = -1.118033989 Solving 1.25 + x = -1.118033989 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = -1.118033989 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = -1.118033989 + -1.25 x = -1.118033989 + -1.25 Combine like terms: -1.118033989 + -1.25 = -2.368033989 x = -2.368033989 Simplifying x = -2.368033989Solution
