R1=r1+r2+r3

2a+3b    2a+3b .  2a+3b

a+2b .       a            a+b

a+b         a+2b          a

taking 2a+3b common

1              1                 1      

a+2b       a               a+b     (2a+3b)

a+b        a+2b           a

c1=c1-c3

c2=c2-c3

0      0            1

b       -b         a+b   (2a+3b)

a       a+b         a    

now expanding the determinant

1(b^2+ab+ab)(2a+3b)

(b^2+2ab)(2a+3b)
