Respuesta :

Option C: (x+4) and (x-1) are the factors of the equation

Explanation:

Given that the equation is [tex]x^{2} +3x-4[/tex]

We need to determine the factors of the equation.

Splitting the middle term, we get,

[tex]x^{2} +4x-x-4[/tex]

Grouping the terms, we have,

[tex]x(x+4)-1(x+4)[/tex]

Let us factor out the term (x+4), we have,

[tex](x+4)(x-1)[/tex]

Thus, the factors of the equation are (x+4) and (x-1)

Hence, Option C is the correct answer.
