Question

6. The area of a rectangular field is given by the trinomial t^2 – 4t – 45. The length of the rectangle is t + 5. What is the expression for the width of the field?

Answer 1

they are telling you that (t+5) is a factor of the trinomial, so you factor the trinomial and get the other binomial

Answer 2

\[{t^2 -4t-45}\over {t+5}\]

Answer 3

(t+5)(t-9)=t^2-4t-45
