Question 722872
We just started solving polynomials by grouping. My teacher said this is a baby step for quadratic equations but I don't really get it.
The problem I need help with is: 2a^2+3a+6a+a
We're supposed to group the first two and last two sets of numbers based on the greatest common factor.
I got this: a(2a+3)+a(6+1)
My teacher said the two groups of numbers in parentheses are supposed to match. Mine doesn't and I got confused.
---------------
1st, polynomials are not solved.  Equations are solved.

I think you mean factoring by grouping.
2a^2+3a+6a+a
That has 3 a terms, I suspect a typo.
= 2a^2 + 10a
= 2a*(a + 5)
