The area of a rectangular painting is given by the trinomial x? + 2x - 15. What are the possible dimensions of the painting? Use factoring.
To find the possible dimensions of the painting, we need to factor the trinomial x^2 + 2x - 15.
x^2 + 2x - 15 can be factored as (x + 5)(x - 3).
Therefore, the possible dimensions of the painting are x + 5 and x - 3.
This means the possible dimensions are:
Length: x + 5
Width: x - 3
