1. Find the remainder when x + 3x + 3x + 1 is divided by
(v) ***
(v) 5+ 2x
2 Find the remainder when x-ar + 6x-a is divided by x-a.
3. Check whether 7 + 3x is a factor of 3r +7x.
​

Answer 1

Answer:

1.let 2x+5=0

x=-5/2

put it in equation

-5/2-15/2-15/2+1

= -33/2

let x-a=0

x=a

2. put x=a in equ.

a-ar+6a-a

=a(6-r)

3. no.
