$2x^2 + x -15$

F.O.I.L.

First, Outer, Inner Last

Multiply your first terms:

(2x - 5)(x + 3)

$2x * x = 2x^2$

Multiply your outer terms:

(2x - 5)(x + 3)

$2x * 3 = 6x$

Multiply your inner terms:

(2x - 5)(x + 3)

$-5 * x = -5x$

Multiply your last terms:

(2x -5)(x + 3)

$-5 * 3 = -15$

Add all your terms together.

$2x^2 + 6x - 5x - 15$

Simplify.

$2x^2 + x -15$

How do you foil (2x-5)(x+3)(2x-5)(x+3)?
