Subproblem 1

Set the factor '(1 + 3g + g2)' equal to zero and attempt to solve: Simplifying 1 + 3g + g2 = 0 Solving 1 + 3g + g2 = 0 Begin completing the square. Move the constant term to the right: Add '-1' to each side of the equation. 1 + 3g + -1 + g2 = 0 + -1 Reorder the terms: 1 + -1 + 3g + g2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 3g + g2 = 0 + -1 3g + g2 = 0 + -1 Combine like terms: 0 + -1 = -1 3g + g2 = -1 The g term is 3g. 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. 3g + 2.25 + g2 = -1 + 2.25 Reorder the terms: 2.25 + 3g + g2 = -1 + 2.25 Combine like terms: -1 + 2.25 = 1.25 2.25 + 3g + g2 = 1.25 Factor a perfect square on the left side: (g + 1.5)(g + 1.5) = 1.25 Calculate the square root of the right side: 1.118033989 Break this problem into two subproblems by setting (g + 1.5) equal to 1.118033989 and -1.118033989.

Subproblem 1

g + 1.5 = 1.118033989 Simplifying g + 1.5 = 1.118033989 Reorder the terms: 1.5 + g = 1.118033989 Solving 1.5 + g = 1.118033989 Solving for variable 'g'. Move all terms containing g to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + g = 1.118033989 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + g = 1.118033989 + -1.5 g = 1.118033989 + -1.5 Combine like terms: 1.118033989 + -1.5 = -0.381966011 g = -0.381966011 Simplifying g = -0.381966011

Subproblem 2

g + 1.5 = -1.118033989 Simplifying g + 1.5 = -1.118033989 Reorder the terms: 1.5 + g = -1.118033989 Solving 1.5 + g = -1.118033989 Solving for variable 'g'. Move all terms containing g to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + g = -1.118033989 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + g = -1.118033989 + -1.5 g = -1.118033989 + -1.5 Combine like terms: -1.118033989 + -1.5 = -2.618033989 g = -2.618033989 Simplifying g = -2.618033989

Solution
