5x2 + 14x - 3

How do you factor

The answer is prime.

Step-by-step explanation:

You can't factor it out.

I'm assuming that the x between 5 and 2 is multiplication. So multiply 5 and 2. That will result in 10. Then add it to - 3. That will result in 7.

You will have 14x + 7.

Factor it by 7. This means dividing each number by 7 ONLY. The variable x will always remain.

Your final answer should be 2x-1.
