A. b= -4 and b= 0
B. b= -4
C. b= 0 and b= 4
D. b= 4

Answer 1

c

Explanation:

Answer 2

Option C is correct.

Explanation:

Given Equation:

`(5)/(3b^3-2b^2-5)=(2)/(b^3-2)`

To find: Solution of the Equation.

Consider,

`5(b^3-2)=2(3b^3-2b^2-5)`

`5b^3-10=6b^3-4b^2-10`

`6b^3-5b^3-4b^2+10-10=0`

`b^3-4b^2=0`

`b^2(b-4)=0`

b² = 0 ⇒ b = 0

b - 4 = 0 ⇒ b = 4

Therefore, Option C is correct.
