Subproblem 1

Set the factor '(-8 + -5x + 2x2)' equal to zero and attempt to solve: Simplifying -8 + -5x + 2x2 = 0 Solving -8 + -5x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -4 + -2.5x + x2 = 0 Move the constant term to the right: Add '4' to each side of the equation. -4 + -2.5x + 4 + x2 = 0 + 4 Reorder the terms: -4 + 4 + -2.5x + x2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -2.5x + x2 = 0 + 4 -2.5x + x2 = 0 + 4 Combine like terms: 0 + 4 = 4 -2.5x + x2 = 4 The x term is -2.5x. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5x + 1.5625 + x2 = 4 + 1.5625 Reorder the terms: 1.5625 + -2.5x + x2 = 4 + 1.5625 Combine like terms: 4 + 1.5625 = 5.5625 1.5625 + -2.5x + x2 = 5.5625 Factor a perfect square on the left side: (x + -1.25)(x + -1.25) = 5.5625 Calculate the square root of the right side: 2.358495283 Break this problem into two subproblems by setting (x + -1.25) equal to 2.358495283 and -2.358495283.

Subproblem 1

x + -1.25 = 2.358495283 Simplifying x + -1.25 = 2.358495283 Reorder the terms: -1.25 + x = 2.358495283 Solving -1.25 + x = 2.358495283 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + x = 2.358495283 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = 2.358495283 + 1.25 x = 2.358495283 + 1.25 Combine like terms: 2.358495283 + 1.25 = 3.608495283 x = 3.608495283 Simplifying x = 3.608495283

Subproblem 2
