Subproblem 1

Set the factor 'x2' equal to zero and attempt to solve: Simplifying x2 = 0 Solving x2 = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x2 = 0 Take the square root of each side: x = {0}

Subproblem 2

Set the factor '(-7 + 3x + x2)' equal to zero and attempt to solve: Simplifying -7 + 3x + x2 = 0 Solving -7 + 3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '7' to each side of the equation. -7 + 3x + 7 + x2 = 0 + 7 Reorder the terms: -7 + 7 + 3x + x2 = 0 + 7 Combine like terms: -7 + 7 = 0 0 + 3x + x2 = 0 + 7 3x + x2 = 0 + 7 Combine like terms: 0 + 7 = 7 3x + x2 = 7 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 7 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 7 + 2.25 Combine like terms: 7 + 2.25 = 9.25 2.25 + 3x + x2 = 9.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 9.25 Calculate the square root of the right side: 3.041381265 Break this problem into two subproblems by setting (x + 1.5) equal to 3.041381265 and -3.041381265.

Subproblem 1

x + 1.5 = 3.041381265 Simplifying x + 1.5 = 3.041381265 Reorder the terms: 1.5 + x = 3.041381265 Solving 1.5 + x = 3.041381265 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 3.041381265 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 3.041381265 + -1.5 x = 3.041381265 + -1.5 Combine like terms: 3.041381265 + -1.5 = 1.541381265 x = 1.541381265 Simplifying x = 1.541381265

Subproblem 2

x + 1.5 = -3.041381265 Simplifying x + 1.5 = -3.041381265 Reorder the terms: 1.5 + x = -3.041381265 Solving 1.5 + x = -3.041381265 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -3.041381265 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -3.041381265 + -1.5 x = -3.041381265 + -1.5 Combine like terms: -3.041381265 + -1.5 = -4.541381265 x = -4.541381265 Simplifying x = -4.541381265
