Answer:
Correct option is
D
2x−3
Given: f(x)=x
4
+2x
3
−13x
2
−12x+21
g(x)=x
2
−4x+3
By division algorithm
f(x)=q(x)×g(x)+r(x)
g(x)=
q(x)
f(x)−r(x)
So. r(x) must be subtracted so, that result is exactly divisible by x
2
−4x+3.
2x−3 must be subtracted from f (x), so that result is exactly divisible by x
2
−4x+3.
I hope it helps you
