Multiply fist and last. Factor out to equal middle. Then group

In problems like 2x^2+3n-9 I keep getting x(x+6)-3(x-3) but don't know if its right or where to go from there

3xy+9x-2y-6 howw would i factor by grouping cant figure it out

This question is about factoring polynomials by grouping, and I am confused on how to solve this problem. Hope you will help me as soon as possible.

In problems like 2x^2+3n-9 I keep getting x(x+6)-3(x-3) but don't know if its right or where to go from there.

a. x^2+2x/x^2-4 b.x^2-5x+4/x^2-1 c. 3x^2-6x/x^2-6x+8 d.x^2+3x-10/x^2-25

factorise each of the following expressions completely a) 6x^2y^2-5xy-4 b) 3z-8xyz+4x^2y^2z c) 36y^2-49(x+1)^2
