Check
wheather
7 + 3x is a
factor of 3 x 2 + 7 x​

Answer 1

Answer:

yes..............yup...ssssss

Answer 2

Step-by-step explanation:

Solution: Apply remainder theorem

=>7 + 3x =0

=> 3x = - 7

=> x = - 7/3

Replace x by - 7/3 we get

=>3x3 + 7x

=>3(-7/3)3 + 7(-7/3)

=>3(-343/27) – 49/3

=> (-343/9) – 49/3

This value is not equal to 0

So that 7 + 3x is not a factor of expression 3x3 + 7x
