Question

4. IfM= 2-C, prove that C+ 6CM+M-8 = 0.​

Answer 1

Step-by-step explanation:

M = 2 - C ¶eq 1

To Prove :

C^3 + 6CM + M^3 - 8

Apply equation 1

C^3 + 6C ( 2-C ) + ( 2-C ) - 8 = 0

C^3 +12C - 6C^2 + 8 - 12 C + 6C^2 + C^3 - 8 = 0

2C^3 = 0

C^3 = 0

C = 0

C = 0 in equation 1

M = 2 - C

M = 2 - 0

M= 2

Hence proved.
