The area of a rectangular classroom is given by the trinomial 10x^2 + 3x - 4 what are the possible dimensions of the classroom? use factoring. a.(5x - 4) and (2x + 1) b.(5x - 4) and (2x - 1) c.(5x + 4) and (2x - 1) d.(5x + 4) and (2x + 1)

C is the correct factored form of the equation.

To solve this, you can factor the polynomial by grouping. There are numerous ways to do this.

If you are given a multiple choice question like this, you can use the FOIL method to test the answers until you get the correct one.

Choice C with the FOIL method.

(5x + 4)(2x - 1)
10x^2 - 5x + 8x - 4
10x^2 +3x - 4

It is correct!
