Answer 1

a

Answer 2

Try rewriting the problem as (4x3 + 2x2 + 0x + 50) (2x + 5).
Then use long division: Your first question would be "how many times does 2x go into 4x3?" Write that answer down, then multiply it by (2x + 5), etc.

Answer 4

Here's a start:

_2x2______________________
(2x + 5) (4x3 + 2x2 + 0x + 50)
4x3 + 10x2 (multiply)
----------
-8x2 + 0x (subtract and bring down the next term


Now, repeat: How many times 2x go into -8x2 ?
