Answer:

Option (2) is correct choice.

Step-by-step explanation:

Given polynomial 3x^2+9x-3

We have factorize the given polynomial and choose the correct from options given.

Factor are the smallest forms a given number is broken such that the product of factors gives back the number we factorized.

Here, 3x^2+9x-3

First taking 3 common from whole expression.

3x^2+9x-3=3(x^2+3x-1)

Thus, option (2) is correct choice.
Factor completely: 3x2 + 9x − 3

3x2 + 9x − 3    (a 3 can be divided from each number)
3(x2+3x-1)

can x2+3x-1 be factored out anymore? no

3(x2+3x-1) is the answer
