Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(-5 + 4x + 2x2)' equal to zero and attempt to solve: Simplifying -5 + 4x + 2x2 = 0 Solving -5 + 4x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -2.5 + 2x + x2 = 0 Move the constant term to the right: Add '2.5' to each side of the equation. -2.5 + 2x + 2.5 + x2 = 0 + 2.5 Reorder the terms: -2.5 + 2.5 + 2x + x2 = 0 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + 2x + x2 = 0 + 2.5 2x + x2 = 0 + 2.5 Combine like terms: 0 + 2.5 = 2.5 2x + x2 = 2.5 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 = 2.5 + 1 Reorder the terms: 1 + 2x + x2 = 2.5 + 1 Combine like terms: 2.5 + 1 = 3.5 1 + 2x + x2 = 3.5 Factor a perfect square on the left side: (x + 1)(x + 1) = 3.5 Calculate the square root of the right side: 1.870828693 Break this problem into two subproblems by setting (x + 1) equal to 1.870828693 and -1.870828693.

Subproblem 1

x + 1 = 1.870828693 Simplifying x + 1 = 1.870828693 Reorder the terms: 1 + x = 1.870828693 Solving 1 + x = 1.870828693 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 = 1.870828693 + -1 Combine like terms: 1 + -1 = 0 0 + x = 1.870828693 + -1 x = 1.870828693 + -1 Combine like terms: 1.870828693 + -1 = 0.870828693 x = 0.870828693 Simplifying x = 0.870828693

Subproblem 2
