Question 718811: How do I solve 15x 2 +31x +2 using the ac method

You can't "solve" it because you have no relational operator, i.e. =, <, >, 
, or 
. I will then presume that you want to factor it.
Multiply the lead coefficient by the constant term: 15 times 2 is 30.
Perform the prime factorization of 30: 2 X 3 X 5. So the two-integer factors of 30 must be 6 X 5, 10 X 3, 15 X 2, or 30 X 1. Examine these pairs for a set that sums to the first degree term coefficient, i.e. 31. Looks like 30 and 1, right?
Rewrite the 1st degree term as a pair of terms that sum to 
Factor by grouping:
\ +\ (x\ +\ 2))
(x\ +\ 2))
