Question

factorize 6xy_4y+6_9

Answer 1

Split       6xy - 9x + 4y - 6 
             into two 2-term polynomials 
              - 9x + 6xy   and     + 4y - 6
             This partition did not result in a factorization. We'll try another one:

             6xy - 9x   and     + 4y - 6
             This partition looks good

 1.2       Pull out from each binomial separately
             6xy - 9x   =   3x • (2y - 3)
              + 4y - 6   =    + 2 • (2y - 3)

 1.3       Add up to arrive at the desired factorization
             (3x + 2) • (2y - 3)

Factorization found :                  (3x + 2) • (2y - 3)

Answer 2

For factorization the degree of the polynomial must have 2
