Question

Check whether 7 + 3x is a factor of 3x3 + 7x.​

Answer 1

hey there

g(x)=3x+7

p(x)=3x³+7x

p(x)÷g(x)

3x+7)3x³+7x(x²-7/3x+70/9

3x³+7x²

--------------

- 7x²+7x

- 7x²-49/3x

------------------

70/3x

70/9x+490/

here remainder is not zero

so,g(x) is not a factor of p(x)

hope the answer helps u
