Question

check whether 7+3x is a factor of 3x^3+7x​

Answer 1

⭐Solution⭐

✒Given here

3x³+7x =0....(1)

✏If (7+3x) is a factor of this equation so,

x = -7/3 exits this equatiosn

✒ 3(-7/3)³+ 7(-7/3)

= 3 × 343/27 - 49/3

= 343 /9 - 49/3

= (343-49×3)/9

= (343-147)/9

= 196/9.

✒Thus:-

✏(7+3x) not factor of equations (1).
