Simplifying (t + 7)(t + -9) = 0 Reorder the terms: (7 + t)(t + -9) = 0 Reorder the terms: (7 + t)(-9 + t) = 0 Multiply (7 + t) * (-9 + t) (7(-9 + t) + t(-9 + t)) = 0 ((-9 * 7 + t * 7) + t(-9 + t)) = 0 ((-63 + 7t) + t(-9 + t)) = 0 (-63 + 7t + (-9 * t + t * t)) = 0 (-63 + 7t + (-9t + t2)) = 0 Combine like terms: 7t + -9t = -2t (-63 + -2t + t2) = 0 Solving -63 + -2t + t2 = 0 Solving for variable 't'. Factor a trinomial. (-7 + -1t)(9 + -1t) = 0Subproblem 1
Set the factor '(-7 + -1t)' equal to zero and attempt to solve: Simplifying -7 + -1t = 0 Solving -7 + -1t = 0 Move all terms containing t to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + -1t = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -1t = 0 + 7 -1t = 0 + 7 Combine like terms: 0 + 7 = 7 -1t = 7 Divide each side by '-1'. t = -7 Simplifying t = -7Subproblem 2
Set the factor '(9 + -1t)' equal to zero and attempt to solve: Simplifying 9 + -1t = 0 Solving 9 + -1t = 0 Move all terms containing t to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + -1t = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -1t = 0 + -9 -1t = 0 + -9 Combine like terms: 0 + -9 = -9 -1t = -9 Divide each side by '-1'. t = 9 Simplifying t = 9Solution
t = {-7, 9}
