Multiplying Linear Expressions in the Real World
A basketball is thrown into the air. Its height after t seconds can be modeled by –4t(4t – 5).

Simplify the expression –4t(4t – 5).

–16t2 + 20t
–16t + 20
16t2 – 20t
–16t2 – 20t

Answer 1

Multiply each term by −4t: (−4t)(4t) = −16t^2 and (−4t)(−5) = +20t. So the simplified expression is −16t^2 + 20t.
