Answer:
6xy - 4y + 6 - 9x = (3x -2)(2y - 3)
Step-by-step explanation:
6xy - 4y + 6 - 9x
Draw pair
= 6xy - 4y + 6 - 9x
Find 2y common on first two terms and 3 from next two terms
= 2y (3x - 2) + 3(2 - 3x)
= 2y (3x - 2) - 3 (3x - 2)
Take (3x -2) common
= (3x -2)(2y - 3)
So, 6xy - 4y + 6 - 9x = (3x -2)(2y - 3)
