x^2-5x-24=color(blue)((x-8)(x+3))x25x24=(x8)(x+3)

Explanation:

The trinomial

x^2-5x-24x25x24

In order to determine the two binomials that are the factors of the trinomial by doing the following:

Determine two numbers that when added equal -55 and when multiplied equal -2424. (You may need to make a list of combinations of numbers to find one that works with your problem.)

The numbers -88 and 33 meet the criteria for this trinomial.

Rewrite the trinomial as two binomials.

(x-8)(x+3)(x8)(x+3)
