Answer:

The answer is B

Step-by-step explanation:

This is to divide the factor already pulled out.

Use 10x^{3} divided by 5x^{2} to get +2x, again to use 35x^{2} divided by 5x^{2} to get +7.

For the 2nd group, since they pulled -2 out, you'll need to divide everything by -2. Use -4x divided by -2 get +7 and use -14 divided by -2 get +7

Therefore, the answer is +2x+7

Answer:

B. 2x + 7

Step-by-step explanation:

I can see where this is tough, lets go through it. Polynomials that are factored need to be able to multiply back into themselves. When looked at a polynomial, you can find a common multiplier for both, but we already have those. The common multipliers are what goes outside of the parenthesis. Now you just need to find what's inside. The numbers inside are going to be the numbers that multiply back to the numbers above. You can go by process of elimination to get rid of options. First, you will do 5 * 2 to get 10, meaning you can remove A and C. Then you see that you have to get to the third power on the 10, and get to x on the 4. This means you will have to have 1x on the first number of the set to ensure you get both of those numbers.

Hope this helped, please mark brainliest i need to feed my family ^_^
