How do you Factorise: 9ax^2 - 9axy + 2ay^2
I understand it now :
9ax^2-9axy+2y=

=a(9x^2-9xy+2y^2)=[2*9=18 factor of 18=(-3)*(-6) and the sum of (-3)+(-6)=-9]

=a(9x^2-3xy-6xy+2y^2)=

=a[3x(3x-y)-2y(3x-y)]=

=a(3x-y)(3x-2y)
5. It's not a quadratic equation so it would be one common factor in all of the terms and then a open bracket with the rest of them in close bracket
