Respuesta :

Answer:

Option D is correct.

Step-by-step explanation:

We have been given:

[tex]x^2+x-12[/tex]

[tex]x^2+4x-3x-12[/tex]

[tex]x(x+4)-3(x+4)[/tex]

[tex](x-3)(x+4)[/tex]

Hence, the zeroes are: -4 and 3

4(-3)=-12

And -3+4=1

Hence, Latisha is correct.

Therefore, Option D is correct.
