Simplifying 6n2 + 12n + 8 = 0 Reorder the terms: 8 + 12n + 6n2 = 0 Solving 8 + 12n + 6n2 = 0 Solving for variable 'n'. Factor out the Greatest Common Factor (GCF), '2'. 2(4 + 6n + 3n2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(4 + 6n + 3n2)' equal to zero and attempt to solve: Simplifying 4 + 6n + 3n2 = 0 Solving 4 + 6n + 3n2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 1.333333333 + 2n + n2 = 0 Move the constant term to the right: Add '-1.333333333' to each side of the equation. 1.333333333 + 2n + -1.333333333 + n2 = 0 + -1.333333333 Reorder the terms: 1.333333333 + -1.333333333 + 2n + n2 = 0 + -1.333333333 Combine like terms: 1.333333333 + -1.333333333 = 0.000000000 0.000000000 + 2n + n2 = 0 + -1.333333333 2n + n2 = 0 + -1.333333333 Combine like terms: 0 + -1.333333333 = -1.333333333 2n + n2 = -1.333333333 The n term is 2n. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2n + 1 + n2 = -1.333333333 + 1 Reorder the terms: 1 + 2n + n2 = -1.333333333 + 1 Combine like terms: -1.333333333 + 1 = -0.333333333 1 + 2n + n2 = -0.333333333 Factor a perfect square on the left side: (n + 1)(n + 1) = -0.333333333 Can't calculate square root of the right side.
