The area of a rectangular room is given by the trinomial 3x^2-13x-30 what are the possible dimensions of the frame? use factoring.

(3x + 5) and (x - 6).

Step-by-step explanation:

3x^2-13x-30

Use the 'ac' method:

a * c = 3*-30 = -90.

We need two numbers whose product is -90 and whose  sum is -13. They are  -18  and + 5, so we have

3x^2 - 18x + 5x - 30     Factor by grouping:

= 3x(x - 6) + 5(x - 6)

= (3x + 5)(x - 6).
