Simplifying t2 = -7t + 8 Reorder the terms: t2 = 8 + -7t Solving t2 = 8 + -7t Solving for variable 't'. Reorder the terms: -8 + 7t + t2 = 8 + -7t + -8 + 7t Reorder the terms: -8 + 7t + t2 = 8 + -8 + -7t + 7t Combine like terms: 8 + -8 = 0 -8 + 7t + t2 = 0 + -7t + 7t -8 + 7t + t2 = -7t + 7t Combine like terms: -7t + 7t = 0 -8 + 7t + t2 = 0 Factor a trinomial. (-8 + -1t)(1 + -1t) = 0Subproblem 1
Set the factor '(-8 + -1t)' equal to zero and attempt to solve: Simplifying -8 + -1t = 0 Solving -8 + -1t = 0 Move all terms containing t to the left, all other terms to the right. Add '8' to each side of the equation. -8 + 8 + -1t = 0 + 8 Combine like terms: -8 + 8 = 0 0 + -1t = 0 + 8 -1t = 0 + 8 Combine like terms: 0 + 8 = 8 -1t = 8 Divide each side by '-1'. t = -8 Simplifying t = -8Subproblem 2
Set the factor '(1 + -1t)' equal to zero and attempt to solve: Simplifying 1 + -1t = 0 Solving 1 + -1t = 0 Move all terms containing t to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1t = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1t = 0 + -1 -1t = 0 + -1 Combine like terms: 0 + -1 = -1 -1t = -1 Divide each side by '-1'. t = 1 Simplifying t = 1Solution
t = {-8, 1}
