Simplifying 12n2 + -12n = 2 Reorder the terms: -12n + 12n2 = 2 Solving -12n + 12n2 = 2 Solving for variable 'n'. Reorder the terms: -2 + -12n + 12n2 = 2 + -2 Combine like terms: 2 + -2 = 0 -2 + -12n + 12n2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-1 + -6n + 6n2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-1 + -6n + 6n2)' equal to zero and attempt to solve: Simplifying -1 + -6n + 6n2 = 0 Solving -1 + -6n + 6n2 = 0 Begin completing the square. Divide all terms by 6 the coefficient of the squared term: Divide each side by '6'. -0.1666666667 + -1n + n2 = 0 Move the constant term to the right: Add '0.1666666667' to each side of the equation. -0.1666666667 + -1n + 0.1666666667 + n2 = 0 + 0.1666666667 Reorder the terms: -0.1666666667 + 0.1666666667 + -1n + n2 = 0 + 0.1666666667 Combine like terms: -0.1666666667 + 0.1666666667 = 0.0000000000 0.0000000000 + -1n + n2 = 0 + 0.1666666667 -1n + n2 = 0 + 0.1666666667 Combine like terms: 0 + 0.1666666667 = 0.1666666667 -1n + n2 = 0.1666666667 The n term is -1n. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1n + 0.25 + n2 = 0.1666666667 + 0.25 Reorder the terms: 0.25 + -1n + n2 = 0.1666666667 + 0.25 Combine like terms: 0.1666666667 + 0.25 = 0.4166666667 0.25 + -1n + n2 = 0.4166666667 Factor a perfect square on the left side: (n + -0.5)(n + -0.5) = 0.4166666667 Calculate the square root of the right side: 0.645497224 Break this problem into two subproblems by setting (n + -0.5) equal to 0.645497224 and -0.645497224.Subproblem 1
n + -0.5 = 0.645497224 Simplifying n + -0.5 = 0.645497224 Reorder the terms: -0.5 + n = 0.645497224 Solving -0.5 + n = 0.645497224 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + n = 0.645497224 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + n = 0.645497224 + 0.5 n = 0.645497224 + 0.5 Combine like terms: 0.645497224 + 0.5 = 1.145497224 n = 1.145497224 Simplifying n = 1.145497224Subproblem 2
n + -0.5 = -0.645497224 Simplifying n + -0.5 = -0.645497224 Reorder the terms: -0.5 + n = -0.645497224 Solving -0.5 + n = -0.645497224 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + n = -0.645497224 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + n = -0.645497224 + 0.5 n = -0.645497224 + 0.5 Combine like terms: -0.645497224 + 0.5 = -0.145497224 n = -0.145497224 Simplifying n = -0.145497224Solution
