Use the grouping method to factor this polynomial completely.
2x + 6x2 + 5x+15

Step-by-step explanation:

The correct expression is

To use the grouping method, we need to group factorable monomials using parentheses. Notice that 2x and 6x² have a common factor 2x; similarly, 5 and 15x have a common factor 5. We can group each pair of monomials using parenthesis, and then factor each one.

Now we can factor the common monomial :

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
