Simplifying (k + -8)(7k + 1) = 0 Reorder the terms: (-8 + k)(7k + 1) = 0 Reorder the terms: (-8 + k)(1 + 7k) = 0 Multiply (-8 + k) * (1 + 7k) (-8(1 + 7k) + k(1 + 7k)) = 0 ((1 * -8 + 7k * -8) + k(1 + 7k)) = 0 ((-8 + -56k) + k(1 + 7k)) = 0 (-8 + -56k + (1 * k + 7k * k)) = 0 (-8 + -56k + (1k + 7k2)) = 0 Combine like terms: -56k + 1k = -55k (-8 + -55k + 7k2) = 0 Solving -8 + -55k + 7k2 = 0 Solving for variable 'k'. Factor a trinomial. (-1 + -7k)(8 + -1k) = 0Subproblem 1
Set the factor '(-1 + -7k)' equal to zero and attempt to solve: Simplifying -1 + -7k = 0 Solving -1 + -7k = 0 Move all terms containing k to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + -7k = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -7k = 0 + 1 -7k = 0 + 1 Combine like terms: 0 + 1 = 1 -7k = 1 Divide each side by '-7'. k = -0.1428571429 Simplifying k = -0.1428571429Subproblem 2
Set the factor '(8 + -1k)' equal to zero and attempt to solve: Simplifying 8 + -1k = 0 Solving 8 + -1k = 0 Move all terms containing k to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + -1k = 0 + -8 Combine like terms: 8 + -8 = 0 0 + -1k = 0 + -8 -1k = 0 + -8 Combine like terms: 0 + -8 = -8 -1k = -8 Divide each side by '-1'. k = 8 Simplifying k = 8Solution
k = {-0.1428571429, 8}
