1)Factor completely: x^2-9y^2
(x+3y)(x-3y)
..
2)Factor Completely: 3w^2z^4-3w^2 and 27z^3+125
3w^2(z^4-1)
3w^2[(z^2+1)(z^2-1)]
3w^2[(z^2+1)(z+1)(z-1)]
..
3) Factor: tu-24t^2+3t^3-8u
3t^3-24t^2+tu-8u
3t^2(t-8)+u(t-8)
(t-8)(3t^2+u)
..
4)Factor: 5x^2+13xy-6y^2
5x^2+15xy-2xy-6y^2
5x(x+3y)+2y(x+3y)
(5x+2y)(x+3y)
