Answer:

1. (x²- 7x+10) ÷ (x-5)

x²-7x+10

----------------

x-5

x²-2x-5x+10

-------------------

x-5

x (x-2)-5+10

-------------------

x-5

x (x-2)-5 (x-2)

----------------------

x-5

(x-2) (x-5)

---------------

x-5

= x-2

2. (x²+x-20) ÷ (x-4)

x²+x-20

----------------

x-4

x²+4x-5x-20

---------------------

x-4

x(x+5)-4(x+5)

----------------------

x-4

(x-4) (x+5)

------------------

x-4

= x+5

3. (x³+ 3x²+5x+3) ÷ (x+1)

x³+3x²+5x+3

----------------------

x+1

x³+x²+2x²+2x+3x+3

--------------------------------

x+1

x²(x+1)+ 2x(x+1)+3(x+1)

---------------------------------

x+1

(x+1) (x²+2x +3)

--------------------------

x+1

= x2+2x+3
