Question

check whether 7+3x is a factor of 3x cube+7x by remaimder theorm plzz give answer by only remainder theorm i mark as brain list plzz

Answer 1

Hii..

here is ur answer :--

g(x) = 7+3x

=> 7+3x=0

=> 3x=-7

=> x=-7/3

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

p(-7/3) = 3* (-7/3)^3 +7*(-7/3)

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

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

= -343+(-49)/ 9

= -343 +(-147)/9

= -490/9

therefore, p (x) ≠ 0

Hence, g(x) is not the factor of p(x).

Hope it helps u!!
