Question

check whether 7+3x is a factor of 3x^3+7x​

Answer 1

No , 7+3x is not factor of 3x³+7x

Step-by-step explanation:

To find whether

is a factor of

find the value of x from f(x) and put to g(x) ,if expression becomes zero than f(x) is a factor of g(x),otherwise

Answer 2

Answer:

g(x)=7+3x

to find divisor zero

7+3x=0

3x=0-7

x=-7/3

therefore,

f(x) =3x^3+7x

f(-7/3)=3(-7/3)^3+7(-7/3)

=3(-343/27)+7(-7/3)

=(-343/9)+(-49/3)

= -343-147/9

= -490/9

= -54.45 answer.

I, hope answer your question
