Use FOIL method and get the following solution #6x^2+x-1#

Explanation:

Use FOIL Method

F- First
O- Outer
I - Inner
L - Last

#(3x-1)(2x+1)#

First terms #(3x)(2x) = 6x^2#
Outer terms #(3x)(+1)=3x#
Inner terms #(-1)(2x) = -2x#
Last terms #(-1)(+1) = -1#
Add all these

#6x^2+3x-2x-1#
#(6x^2+x-1)#

#(3x-1)(2x+1)= 6x^2+x-1# answer
