x^2-9x+18 \\ \\ (x - 6)(x - 3) \\ \\

The final result is: (x - 6)(x - 3).

----------


x^2-49 \\ \\ x^2 - 7^2 \\ \\ (x + 7)(x - 7) \\ \\

The final result is: (x + 7)(x - 7).

-----------


2y^3+4y^2-30y \\ \\ GCF = 2y \\ \\ 2y( (2y^3)/(2y) + (4y^2)/(2y) + (-30y)/(2y) ) \\ \\ 2y(y^2 + 2y - 15) \\ \\ 2y(y - 3)(y + 5) \\ \\

The final result is: 2y(y - 3)(y + 5).
