Simplifying 25x2 + -40x + -16 = 0 Reorder the terms: -16 + -40x + 25x2 = 0 Solving -16 + -40x + 25x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 25 the coefficient of the squared term: Divide each side by '25'. -0.64 + -1.6x + x2 = 0 Move the constant term to the right: Add '0.64' to each side of the equation. -0.64 + -1.6x + 0.64 + x2 = 0 + 0.64 Reorder the terms: -0.64 + 0.64 + -1.6x + x2 = 0 + 0.64 Combine like terms: -0.64 + 0.64 = 0.00 0.00 + -1.6x + x2 = 0 + 0.64 -1.6x + x2 = 0 + 0.64 Combine like terms: 0 + 0.64 = 0.64 -1.6x + x2 = 0.64 The x term is -1.6x. Take half its coefficient (-0.8). Square it (0.64) and add it to both sides. Add '0.64' to each side of the equation. -1.6x + 0.64 + x2 = 0.64 + 0.64 Reorder the terms: 0.64 + -1.6x + x2 = 0.64 + 0.64 Combine like terms: 0.64 + 0.64 = 1.28 0.64 + -1.6x + x2 = 1.28 Factor a perfect square on the left side: (x + -0.8)(x + -0.8) = 1.28 Calculate the square root of the right side: 1.13137085 Break this problem into two subproblems by setting (x + -0.8) equal to 1.13137085 and -1.13137085.Subproblem 1
x + -0.8 = 1.13137085 Simplifying x + -0.8 = 1.13137085 Reorder the terms: -0.8 + x = 1.13137085 Solving -0.8 + x = 1.13137085 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.8' to each side of the equation. -0.8 + 0.8 + x = 1.13137085 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + x = 1.13137085 + 0.8 x = 1.13137085 + 0.8 Combine like terms: 1.13137085 + 0.8 = 1.93137085 x = 1.93137085 Simplifying x = 1.93137085Subproblem 2
x + -0.8 = -1.13137085 Simplifying x + -0.8 = -1.13137085 Reorder the terms: -0.8 + x = -1.13137085 Solving -0.8 + x = -1.13137085 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.8' to each side of the equation. -0.8 + 0.8 + x = -1.13137085 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + x = -1.13137085 + 0.8 x = -1.13137085 + 0.8 Combine like terms: -1.13137085 + 0.8 = -0.33137085 x = -0.33137085 Simplifying x = -0.33137085Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.93137085, -0.33137085}
