Simplifying 7n2 + 56 = 42n Reorder the terms: 56 + 7n2 = 42n Solving 56 + 7n2 = 42n Solving for variable 'n'. Reorder the terms: 56 + -42n + 7n2 = 42n + -42n Combine like terms: 42n + -42n = 0 56 + -42n + 7n2 = 0 Factor out the Greatest Common Factor (GCF), '7'. 7(8 + -6n + n2) = 0 Factor a trinomial. 7((2 + -1n)(4 + -1n)) = 0 Ignore the factor 7.Subproblem 1
Set the factor '(2 + -1n)' equal to zero and attempt to solve: Simplifying 2 + -1n = 0 Solving 2 + -1n = 0 Move all terms containing n to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -1n = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1n = 0 + -2 -1n = 0 + -2 Combine like terms: 0 + -2 = -2 -1n = -2 Divide each side by '-1'. n = 2 Simplifying n = 2Subproblem 2
Set the factor '(4 + -1n)' equal to zero and attempt to solve: Simplifying 4 + -1n = 0 Solving 4 + -1n = 0 Move all terms containing n to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + -1n = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1n = 0 + -4 -1n = 0 + -4 Combine like terms: 0 + -4 = -4 -1n = -4 Divide each side by '-1'. n = 4 Simplifying n = 4Solution
