Answer:
Step-by-step explanation:
1)x^2+px-qx-pq
=x(x+p)-q(x+p)
=(x-q)(x+p)
=(x+p)(x-q)
2)x^3-x^2y^2-xy+y^3
=x^2(x-y^2)-y^2(x-y^2)
=(x^2-y^2)(x^2-y^2)
=(x-y)(x+y)(x^2_y)
=(x-y^2)(x^2+y)
3) I don't know sorry!
4)6y^2-9ay+4by-6ab
=3y(2y-3a)+2b(2y-3a)
=(2y-3a)(3y+2b)
5)t^3-t^2+t-1
=t^3+t-1t^2-1
=t(t^2+1)-1(t^2+1)
=(t-1)(t^2+1)
sorry for 3
