Simplifying 8x2 + -1x + -80 = 0 Reorder the terms: -80 + -1x + 8x2 = 0 Solving -80 + -1x + 8x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -10 + -0.125x + x2 = 0 Move the constant term to the right: Add '10' to each side of the equation. -10 + -0.125x + 10 + x2 = 0 + 10 Reorder the terms: -10 + 10 + -0.125x + x2 = 0 + 10 Combine like terms: -10 + 10 = 0 0 + -0.125x + x2 = 0 + 10 -0.125x + x2 = 0 + 10 Combine like terms: 0 + 10 = 10 -0.125x + x2 = 10 The x term is -0.125x. Take half its coefficient (-0.0625). Square it (0.00390625) and add it to both sides. Add '0.00390625' to each side of the equation. -0.125x + 0.00390625 + x2 = 10 + 0.00390625 Reorder the terms: 0.00390625 + -0.125x + x2 = 10 + 0.00390625 Combine like terms: 10 + 0.00390625 = 10.00390625 0.00390625 + -0.125x + x2 = 10.00390625 Factor a perfect square on the left side: (x + -0.0625)(x + -0.0625) = 10.00390625 Calculate the square root of the right side: 3.162895232 Break this problem into two subproblems by setting (x + -0.0625) equal to 3.162895232 and -3.162895232.Subproblem 1
x + -0.0625 = 3.162895232 Simplifying x + -0.0625 = 3.162895232 Reorder the terms: -0.0625 + x = 3.162895232 Solving -0.0625 + x = 3.162895232 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.0625' to each side of the equation. -0.0625 + 0.0625 + x = 3.162895232 + 0.0625 Combine like terms: -0.0625 + 0.0625 = 0.0000 0.0000 + x = 3.162895232 + 0.0625 x = 3.162895232 + 0.0625 Combine like terms: 3.162895232 + 0.0625 = 3.225395232 x = 3.225395232 Simplifying x = 3.225395232Subproblem 2
x + -0.0625 = -3.162895232 Simplifying x + -0.0625 = -3.162895232 Reorder the terms: -0.0625 + x = -3.162895232 Solving -0.0625 + x = -3.162895232 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.0625' to each side of the equation. -0.0625 + 0.0625 + x = -3.162895232 + 0.0625 Combine like terms: -0.0625 + 0.0625 = 0.0000 0.0000 + x = -3.162895232 + 0.0625 x = -3.162895232 + 0.0625 Combine like terms: -3.162895232 + 0.0625 = -3.100395232 x = -3.100395232 Simplifying x = -3.100395232Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.225395232, -3.100395232}
