chesk wether 7+3x is a factor of 3x^3+7x

Answer 1

Hey friend✋! here is your answer

_____________________________

✔️To check - 7+3x is factor of 3x^3+7x

✔️7+3x=0

✔️3x=-7

✔️x=-7/3

✅Put value of x in given equation

✔️3(-7/3)^3+7(-7/3)

✔️-343/9-49/3 (3^3 cuts with 3)

✔️Take LCM ( 9 is the LCM)

✔️-343-49×3/9

✔️-343-147/9

✅-590/9

Here remainder is -590/9 & 7+3x is not factor of 3x^3+7x because remainder is not 0.
