Answer 1

Friendly tip, next time you post a question, add choices.

ANSWER: (x + 4) and (x – 1)

Explanation:

Answer 2

The factors of
`x^(2)+3x-4` are
`(x+4)` and
`(x-1)`

Explanation:

We need to factorize the expression
`x^(2)+3x-4`

break 3x as 4x - x

`x^(2)+3x-4`

`x^(2)-x+4x-4`

take the common factor out

`x(x-1)+4(x-1)`

take (x-1) common,

`(x+4)(x-1)`

Therefore, the factors of
`x^(2)+3x-4` are
`(x+4)` and
`(x-1)`
