Question

If f(x) is divided by ax+b, then the remainder is

a) f(-a/b) b) f(-b/a) c) f(a/b) d) f(b/a)

Please give step-by-step solution.​

Answer 1

Answer:

Correct option is

A

f(

a

−b

)

The remainder of the polynomial can be found by using remainder theorem.

First equating ax+b to zero we get the value of x,

ax+b=0

ax=−b

∴ x=

a

−b

.

∴ According to the remainder theorem, Remainder is f(

a

−b

) when divided by ax+b
