Simplifying 3g2 + 15g + 10 = 0 Reorder the terms: 10 + 15g + 3g2 = 0 Solving 10 + 15g + 3g2 = 0 Solving for variable 'g'. Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 3.333333333 + 5g + g2 = 0 Move the constant term to the right: Add '-3.333333333' to each side of the equation. 3.333333333 + 5g + -3.333333333 + g2 = 0 + -3.333333333 Reorder the terms: 3.333333333 + -3.333333333 + 5g + g2 = 0 + -3.333333333 Combine like terms: 3.333333333 + -3.333333333 = 0.000000000 0.000000000 + 5g + g2 = 0 + -3.333333333 5g + g2 = 0 + -3.333333333 Combine like terms: 0 + -3.333333333 = -3.333333333 5g + g2 = -3.333333333 The g term is 5g. 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. 5g + 6.25 + g2 = -3.333333333 + 6.25 Reorder the terms: 6.25 + 5g + g2 = -3.333333333 + 6.25 Combine like terms: -3.333333333 + 6.25 = 2.916666667 6.25 + 5g + g2 = 2.916666667 Factor a perfect square on the left side: (g + 2.5)(g + 2.5) = 2.916666667 Calculate the square root of the right side: 1.707825128 Break this problem into two subproblems by setting (g + 2.5) equal to 1.707825128 and -1.707825128.Subproblem 1
g + 2.5 = 1.707825128 Simplifying g + 2.5 = 1.707825128 Reorder the terms: 2.5 + g = 1.707825128 Solving 2.5 + g = 1.707825128 Solving for variable 'g'. Move all terms containing g to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + g = 1.707825128 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + g = 1.707825128 + -2.5 g = 1.707825128 + -2.5 Combine like terms: 1.707825128 + -2.5 = -0.792174872 g = -0.792174872 Simplifying g = -0.792174872Subproblem 2
g + 2.5 = -1.707825128 Simplifying g + 2.5 = -1.707825128 Reorder the terms: 2.5 + g = -1.707825128 Solving 2.5 + g = -1.707825128 Solving for variable 'g'. Move all terms containing g to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + g = -1.707825128 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + g = -1.707825128 + -2.5 g = -1.707825128 + -2.5 Combine like terms: -1.707825128 + -2.5 = -4.207825128 g = -4.207825128 Simplifying g = -4.207825128Solution
The solution to the problem is based on the solutions from the subproblems. g = {-0.792174872, -4.207825128}
