f(x) is a polynomial number. If f(x) is divided by (x-1) and (x-2) then the remainders are respectably 4 and 10. If f(x) is divided by (x-1)(x-2) then what will be the remainder?
please give answer and please please please show the process how to get answer of it.
please give correct answer.
I really need it.

Answer:
Step-by-step explanation:
let f x =(x-1)q(x)+4
so f(1)=4--------(1)
now f(x)=(x-2)*q(x)+10
so f(2)=10-----(2)
now let remainder be ax+b when f(x) is divided by(x-1)(x-2)
so
f(x)=(x-1)(x-2)g(x)+(ax+b)
putting values of 1 and 2 in the above equation
4=a+b
10=2a+b
solving we will get
a=6
and b=-2
hope it helps
