Simplify 6a2 2ab 3ay by9a2 b3Solution 6a2 2ab 3ay by 9a2

Simplify 6a^2 - 2ab + 3ay - by/9a^2 - b^3

( 6a^2 -2ab +3ay -by )/(9a^2 - b^3)

( 6a^2 -2ab +3ay -by) = 2a(3a - b) +y( 3a -b)

= ( 2a +y)( 3a -b)

It seem the term in numerator is b^2 not b^3.

If it is b^3 then: ( 6a^2 -2ab +3ay -by )/(9a^2 - b^3) = ( 2a +y)( 3a -b)/( 9a^2 - b^3)

If it is b^2 then : (( 6a^2 -2ab +3ay -by )/(9a^2 - b^3) = ( 2a +y)( 3a -b)/ (3a +b)(3a -b)

= (2a +y)/(3a +b) -----> (3a -b) gets cancelled
