Question

Which of the following shows the factors of 9x^2 + 3x - 2?

Answer 1

Answer:

Option C. (3x + 2)(3x - 1) is the answer.

Step-by-step explanation:

The given expression is 9x² + 3x - 2 and we have to factorize the expression given.

9x² + 3x - 2 = 9x² + 6x - 3x - 2

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

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

So the factorized form of the expression is (3x + 2)(3x - 1).

Option C is the correct answer.

Answer 2

Answer:

Choice C is the answer.

Step-by-step explanation:

We have given an expression.

9x²+3x-2

We have to factorize given expression.

Split the middle term of above expression so that the sum of two terms should be 3 and their product be -18.

9x²+6x-3x-2

Making groups and taking common , we have

3x(3x+2)-1(3x+2)

Taking 3x+2 as common, we have

(3x+2)(3x-1) which is the answer.
