Simplifying 8x2 + -16x + -18 = 0 Reorder the terms: -18 + -16x + 8x2 = 0 Solving -18 + -16x + 8x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(-9 + -8x + 4x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-9 + -8x + 4x2)' equal to zero and attempt to solve: Simplifying -9 + -8x + 4x2 = 0 Solving -9 + -8x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -2.25 + -2x + x2 = 0 Move the constant term to the right: Add '2.25' to each side of the equation. -2.25 + -2x + 2.25 + x2 = 0 + 2.25 Reorder the terms: -2.25 + 2.25 + -2x + x2 = 0 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + -2x + x2 = 0 + 2.25 -2x + x2 = 0 + 2.25 Combine like terms: 0 + 2.25 = 2.25 -2x + x2 = 2.25 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = 2.25 + 1 Reorder the terms: 1 + -2x + x2 = 2.25 + 1 Combine like terms: 2.25 + 1 = 3.25 1 + -2x + x2 = 3.25 Factor a perfect square on the left side: (x + -1)(x + -1) = 3.25 Calculate the square root of the right side: 1.802775638 Break this problem into two subproblems by setting (x + -1) equal to 1.802775638 and -1.802775638.Subproblem 1
x + -1 = 1.802775638 Simplifying x + -1 = 1.802775638 Reorder the terms: -1 + x = 1.802775638 Solving -1 + x = 1.802775638 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 1.802775638 + 1 Combine like terms: -1 + 1 = 0 0 + x = 1.802775638 + 1 x = 1.802775638 + 1 Combine like terms: 1.802775638 + 1 = 2.802775638 x = 2.802775638 Simplifying x = 2.802775638Subproblem 2
x + -1 = -1.802775638 Simplifying x + -1 = -1.802775638 Reorder the terms: -1 + x = -1.802775638 Solving -1 + x = -1.802775638 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = -1.802775638 + 1 Combine like terms: -1 + 1 = 0 0 + x = -1.802775638 + 1 x = -1.802775638 + 1 Combine like terms: -1.802775638 + 1 = -0.802775638 x = -0.802775638 Simplifying x = -0.802775638Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.802775638, -0.802775638}Solution
x = {2.802775638, -0.802775638}
