1. Do you mean(-3x^2+5x-7)÷(x+2)?
(-3,5,-7)÷(1,2)
= -3, .....(11,-7)÷(1,2)
= (-3x+11).....(-31)

2.(x^3+2x^2-5x+10)÷(x^2-2x+3)
(1,2,-5,10)÷(1,-2,3)
=1, .....(4,-7,10)÷(1,-2,3)
=(x+4)....(x-2)

3.(11+4p-p^2)÷(2+p)=(-p^2+4p+11)÷(p+2)
(-1,4,11)÷(1,2)
=-1,......(6,11)÷(1,2)
=(-p+6).....(-1)
=(6-p)......(-1)

4.(h^3+6h+5)÷(h-2)
(1,0,6,5)÷(1,-2)
=1,......(2,6,5)÷(1,-2)
=1,2,......(2,5)÷(1,-2)
=(h^2+2h+2)......(9)
