Multiply the lead coefficient on the quadratic trinomial by the constant: 10 times 3 is 30. Find two factors of 30 that add up to 17. Try 15 and 2.
Split the first degree term into two parts, 
and 
Group the factors into pairs:
\ +\ \left(2a\ +\ 3\right)\right))
Factor out 
from the first pair of factors:
\ +\ \left(2a\ +\ 3\right)\right))
Factor out 1 from the second pair
\ +\ 1\left(2a\ +\ 3\right)\right))
Factor out )
\left(2a\ +\ 3\right))
