Simplifying -1x2 + -4x + 32.01 = 0 Reorder the terms: 32.01 + -4x + -1x2 = 0 Solving 32.01 + -4x + -1x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -32.01 + 4x + x2 = 0 Move the constant term to the right: Add '32.01' to each side of the equation. -32.01 + 4x + 32.01 + x2 = 0 + 32.01 Reorder the terms: -32.01 + 32.01 + 4x + x2 = 0 + 32.01 Combine like terms: -32.01 + 32.01 = 0.00 0.00 + 4x + x2 = 0 + 32.01 4x + x2 = 0 + 32.01 Combine like terms: 0 + 32.01 = 32.01 4x + x2 = 32.01 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 = 32.01 + 4 Reorder the terms: 4 + 4x + x2 = 32.01 + 4 Combine like terms: 32.01 + 4 = 36.01 4 + 4x + x2 = 36.01 Factor a perfect square on the left side: (x + 2)(x + 2) = 36.01 Calculate the square root of the right side: 6.000833275 Break this problem into two subproblems by setting (x + 2) equal to 6.000833275 and -6.000833275.Subproblem 1
x + 2 = 6.000833275 Simplifying x + 2 = 6.000833275 Reorder the terms: 2 + x = 6.000833275 Solving 2 + x = 6.000833275 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 = 6.000833275 + -2 Combine like terms: 2 + -2 = 0 0 + x = 6.000833275 + -2 x = 6.000833275 + -2 Combine like terms: 6.000833275 + -2 = 4.000833275 x = 4.000833275 Simplifying x = 4.000833275Subproblem 2
x + 2 = -6.000833275 Simplifying x + 2 = -6.000833275 Reorder the terms: 2 + x = -6.000833275 Solving 2 + x = -6.000833275 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 = -6.000833275 + -2 Combine like terms: 2 + -2 = 0 0 + x = -6.000833275 + -2 x = -6.000833275 + -2 Combine like terms: -6.000833275 + -2 = -8.000833275 x = -8.000833275 Simplifying x = -8.000833275Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.000833275, -8.000833275}
