Simplifying (8n + 3)(n + -5) = 0 Reorder the terms: (3 + 8n)(n + -5) = 0 Reorder the terms: (3 + 8n)(-5 + n) = 0 Multiply (3 + 8n) * (-5 + n) (3(-5 + n) + 8n * (-5 + n)) = 0 ((-5 * 3 + n * 3) + 8n * (-5 + n)) = 0 ((-15 + 3n) + 8n * (-5 + n)) = 0 (-15 + 3n + (-5 * 8n + n * 8n)) = 0 (-15 + 3n + (-40n + 8n2)) = 0 Combine like terms: 3n + -40n = -37n (-15 + -37n + 8n2) = 0 Solving -15 + -37n + 8n2 = 0 Solving for variable 'n'. Factor a trinomial. (-3 + -8n)(5 + -1n) = 0Subproblem 1
Set the factor '(-3 + -8n)' equal to zero and attempt to solve: Simplifying -3 + -8n = 0 Solving -3 + -8n = 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 + -8n = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -8n = 0 + 3 -8n = 0 + 3 Combine like terms: 0 + 3 = 3 -8n = 3 Divide each side by '-8'. n = -0.375 Simplifying n = -0.375Subproblem 2
Set the factor '(5 + -1n)' equal to zero and attempt to solve: Simplifying 5 + -1n = 0 Solving 5 + -1n = 0 Move all terms containing n to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + -1n = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -1n = 0 + -5 -1n = 0 + -5 Combine like terms: 0 + -5 = -5 -1n = -5 Divide each side by '-1'. n = 5 Simplifying n = 5Solution
n = {-0.375, 5}
