Subproblem 1

Set the factor '(1 + 5n + -4n2)' equal to zero and attempt to solve: Simplifying 1 + 5n + -4n2 = 0 Solving 1 + 5n + -4n2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -0.25 + -1.25n + n2 = 0 Move the constant term to the right: Add '0.25' to each side of the equation. -0.25 + -1.25n + 0.25 + n2 = 0 + 0.25 Reorder the terms: -0.25 + 0.25 + -1.25n + n2 = 0 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + -1.25n + n2 = 0 + 0.25 -1.25n + n2 = 0 + 0.25 Combine like terms: 0 + 0.25 = 0.25 -1.25n + n2 = 0.25 The n term is -1.25n. Take half its coefficient (-0.625). Square it (0.390625) and add it to both sides. Add '0.390625' to each side of the equation. -1.25n + 0.390625 + n2 = 0.25 + 0.390625 Reorder the terms: 0.390625 + -1.25n + n2 = 0.25 + 0.390625 Combine like terms: 0.25 + 0.390625 = 0.640625 0.390625 + -1.25n + n2 = 0.640625 Factor a perfect square on the left side: (n + -0.625)(n + -0.625) = 0.640625 Calculate the square root of the right side: 0.80039053 Break this problem into two subproblems by setting (n + -0.625) equal to 0.80039053 and -0.80039053.

Subproblem 1

n + -0.625 = 0.80039053 Simplifying n + -0.625 = 0.80039053 Reorder the terms: -0.625 + n = 0.80039053 Solving -0.625 + n = 0.80039053 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '0.625' to each side of the equation. -0.625 + 0.625 + n = 0.80039053 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + n = 0.80039053 + 0.625 n = 0.80039053 + 0.625 Combine like terms: 0.80039053 + 0.625 = 1.42539053 n = 1.42539053 Simplifying n = 1.42539053

Subproblem 2

n + -0.625 = -0.80039053 Simplifying n + -0.625 = -0.80039053 Reorder the terms: -0.625 + n = -0.80039053 Solving -0.625 + n = -0.80039053 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '0.625' to each side of the equation. -0.625 + 0.625 + n = -0.80039053 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + n = -0.80039053 + 0.625 n = -0.80039053 + 0.625 Combine like terms: -0.80039053 + 0.625 = -0.17539053 n = -0.17539053 Simplifying n = -0.17539053
