The polynomials f(x) and g(x) are defined above.
the following polynomials is divisible by
option a)
=> h(x)=f(x)+g(x)= 2x^3+6x^2+4x+x^2+3x+2
Now , divide
2x^3+7x^2+7x+2 ÷ 2x+3
We get ,
Reminder : 1/2
1/2 ≠ 0
So , this is not the answer
Option b)
=> p(x)=f(x)+3g(x) = 2x^3+6x^2+ 4x +3(x^2+3x+2)
= 2x^3+6x^2+4x+3x^2+9x+6
= 2x^3+9x^2+13x+6 ÷ 2x+3
We get ,
Reminder : 0
∴ p(x) =f(x)+3g(x) is satisfying
So ,
Answer is Option b
