Simplifying 8x2 + -54x + -90 = 0 Reorder the terms: -90 + -54x + 8x2 = 0 Solving -90 + -54x + 8x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(-45 + -27x + 4x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-45 + -27x + 4x2)' equal to zero and attempt to solve: Simplifying -45 + -27x + 4x2 = 0 Solving -45 + -27x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -11.25 + -6.75x + x2 = 0 Move the constant term to the right: Add '11.25' to each side of the equation. -11.25 + -6.75x + 11.25 + x2 = 0 + 11.25 Reorder the terms: -11.25 + 11.25 + -6.75x + x2 = 0 + 11.25 Combine like terms: -11.25 + 11.25 = 0.00 0.00 + -6.75x + x2 = 0 + 11.25 -6.75x + x2 = 0 + 11.25 Combine like terms: 0 + 11.25 = 11.25 -6.75x + x2 = 11.25 The x term is -6.75x. Take half its coefficient (-3.375). Square it (11.390625) and add it to both sides. Add '11.390625' to each side of the equation. -6.75x + 11.390625 + x2 = 11.25 + 11.390625 Reorder the terms: 11.390625 + -6.75x + x2 = 11.25 + 11.390625 Combine like terms: 11.25 + 11.390625 = 22.640625 11.390625 + -6.75x + x2 = 22.640625 Factor a perfect square on the left side: (x + -3.375)(x + -3.375) = 22.640625 Calculate the square root of the right side: 4.758216578 Break this problem into two subproblems by setting (x + -3.375) equal to 4.758216578 and -4.758216578.Subproblem 1
x + -3.375 = 4.758216578 Simplifying x + -3.375 = 4.758216578 Reorder the terms: -3.375 + x = 4.758216578 Solving -3.375 + x = 4.758216578 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.375' to each side of the equation. -3.375 + 3.375 + x = 4.758216578 + 3.375 Combine like terms: -3.375 + 3.375 = 0.000 0.000 + x = 4.758216578 + 3.375 x = 4.758216578 + 3.375 Combine like terms: 4.758216578 + 3.375 = 8.133216578 x = 8.133216578 Simplifying x = 8.133216578Subproblem 2
x + -3.375 = -4.758216578 Simplifying x + -3.375 = -4.758216578 Reorder the terms: -3.375 + x = -4.758216578 Solving -3.375 + x = -4.758216578 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.375' to each side of the equation. -3.375 + 3.375 + x = -4.758216578 + 3.375 Combine like terms: -3.375 + 3.375 = 0.000 0.000 + x = -4.758216578 + 3.375 x = -4.758216578 + 3.375 Combine like terms: -4.758216578 + 3.375 = -1.383216578 x = -1.383216578 Simplifying x = -1.383216578Solution
