Subproblem 1

Set the factor '(-3 + -5x + x2)' equal to zero and attempt to solve: Simplifying -3 + -5x + x2 = 0 Solving -3 + -5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '3' to each side of the equation. -3 + -5x + 3 + x2 = 0 + 3 Reorder the terms: -3 + 3 + -5x + x2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -5x + x2 = 0 + 3 -5x + x2 = 0 + 3 Combine like terms: 0 + 3 = 3 -5x + x2 = 3 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = 3 + 6.25 Reorder the terms: 6.25 + -5x + x2 = 3 + 6.25 Combine like terms: 3 + 6.25 = 9.25 6.25 + -5x + x2 = 9.25 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 9.25 Calculate the square root of the right side: 3.041381265 Break this problem into two subproblems by setting (x + -2.5) equal to 3.041381265 and -3.041381265.

Subproblem 1

x + -2.5 = 3.041381265 Simplifying x + -2.5 = 3.041381265 Reorder the terms: -2.5 + x = 3.041381265 Solving -2.5 + x = 3.041381265 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = 3.041381265 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = 3.041381265 + 2.5 x = 3.041381265 + 2.5 Combine like terms: 3.041381265 + 2.5 = 5.541381265 x = 5.541381265 Simplifying x = 5.541381265
