Simplifying 2n2 = -1n + 6 Reorder the terms: 2n2 = 6 + -1n Solving 2n2 = 6 + -1n Solving for variable 'n'. Reorder the terms: -6 + n + 2n2 = 6 + -1n + -6 + n Reorder the terms: -6 + n + 2n2 = 6 + -6 + -1n + n Combine like terms: 6 + -6 = 0 -6 + n + 2n2 = 0 + -1n + n -6 + n + 2n2 = -1n + n Combine like terms: -1n + n = 0 -6 + n + 2n2 = 0 Factor a trinomial. (-2 + -1n)(3 + -2n) = 0Subproblem 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 '(3 + -2n)' equal to zero and attempt to solve: Simplifying 3 + -2n = 0 Solving 3 + -2n = 0 Move all terms containing n to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -2n = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -2n = 0 + -3 -2n = 0 + -3 Combine like terms: 0 + -3 = -3 -2n = -3 Divide each side by '-2'. n = 1.5 Simplifying n = 1.5Solution
n = {-2, 1.5}
