Question

check whether 7+3x is a factor of 3x³ + 7x .

who will answer ❤ correct i will mark brainlist ........ ​

Answer 1

Answer:

no

as you promise mark me as brilianst

Answer 2

put divisor=0

7+3x =0

3x= -7

x= -7/3

step 2

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

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

-3(7^3/3^4) -49/3

-343-147/9

- 590/9

since remainder is not zero

thus, 7x+3 is not the factor of 3x^3+ 7x
