factor by grouping 49xy18y2xSolutionWe have 4 9xy 18y 2x 4

factor by grouping

4+9xy-18y-2x

Solution

We have

4 + 9xy -18y -2x

= 4 - 2x + 9xy -18y

=2(2-x) + 9y(x-2)

= - 2(x-2) + 9y(x-2)

= (x-2)(-2+9y)

=(x-2)(9y-2)

Thus

Factor of 4 + 9xy -18y -2x is (x-2)(9y-2), i.e.

4 + 9xy -18y -2x = (x-2)(9y-2)
