Question

A rocket is fired vertically into the air at 40 m/s. The expression

--5+2 + 40t + 20 gives the rocket's height after t seconds. Factor this
expression.

Answer 1

-5(t² - 8t - 4)

Explanation:

Step 1: Define

-5t² + 40t + 20

Step 2: Simplify

1. Factor - GCF: -5(t² - 8t - 4)

Here, we cannot factor the quadratic and to solve for the roots we will need to use the Quadratic Formula.
