Answer:

[tex](x-7)(x+4)[/tex]

Step-by-step explanation:

To factor the equation, break it into two binomials which multiply to make the equation. To write these binomials (x+a)(x+b), find factors which multiply to -28 and add to -3 for a and b.

28: 1,2,4,7,14,28

-7+4 = -3

[tex]x^2-3x-28 = (x-7)(x+4)[/tex]
