$2x^2 - 5x - 12$

I may be wrong, but did you mean "expand" instead of "factor"?

I went with "expand" as you requested a trinomial.

$(x - 4)(2x + 3)$

FOIL time!!!

$2x^2 + 3x - 8x - 12$
$2x^2 - 5x - 12$

$(x-4)(2x+3)=2x^2-5x-12$

You need to multiply the two binomials to get a trinomial. Use the FOIL method, which shows the order of multiplication.

![ www.mesacc.edu )

$(x-4)(2x+3)=x*2x+x*3+(-4*2x)+(-4*3)$

$(x-4)(2x+3)=2x^2+3x-8x-12$

$(x-4)(2x+3)=2x^2-5x-12$

How do you expand (x-4)(2x+3)(x-4)(2x+3) to get a trinomial?
