40t + -8t3 = 0

Factor out the Greatest Common Factor (GCF), '8t'.
8t(5 + -1t2) = 0

Ignore the factor 8.

Subproblem 1

Set the factor 't' equal to zero and attempt to solve: Simplifying t = 0 Solving t = 0 Move all terms containing t to the left, all other terms to the right. Simplifying t = 0

Subproblem 2

Set the factor '(5 + -1t2)' equal to zero and attempt to solve: Simplifying 5 + -1t2 = 0 Solving 5 + -1t2 = 0 Move all terms containing t to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + -1t2 = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -1t2 = 0 + -5 -1t2 = 0 + -5 Combine like terms: 0 + -5 = -5 -1t2 = -5 Divide each side by '-1'. t2 = 5 Simplifying t2 = 5 Take the square root of each side: t = {-2.236067978, 2.236067978}

Solution

t = {0, -2.236067978, 2.236067978}
