Answer:
Step-by-step explanation:
It's given that :-
p (x) =
And
f (x) = x - 2
Also
p (x) when divided by f (x) leaves remainder 11
---
x - 2 = 0
Solve it further
=》
Put the value in p (x) :-
=》 = 11
Solve it further
=》 8 - 8 - 2k + 5 = 11
Some more steps to go
=》 (-2k) = 11 - 5
Last one step
=》 k = ( -3 )
Now, the second part of the question is :-
Find the zeroes of the given polynomial :-
p (x) =
Factors of 1 are = (-1) and (+1)
Now, when, x = (-1)
=》
Just simplify it further
=》 (-1) + 3 - 3 + 1
Last one step to go
=》 0
Thus, it's a factor of p (x)
Hence, (x + 1) is a factor of p (x)
