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]
