The area of a rectangular field is given by the trinomial t2 – 4t – 45. The length of the rectangle is t + 5. What is the expression for the width of the field?

1 answer

To find the width of the field, we first need to factor the trinomial t^2 - 4t - 45.

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

Therefore, the width of the field is t - 9.
