Question

If x-2/x=3 find x^3-8/x^3

Answer 1

Heya!

If x-2/x = 3

Then, x-2 = 3x

-2 = 3x-x

-2 = 2x

x = -1.

Now,A/Q

x^3-8/x^3 = -1^3-8/-1^3 = -1-8/-1 = -9/-1 = 9

Hope it helps...

____________________

x - 2 / x = 3

ᴏʀ , 3x = x - 2 

ᴏʀ , 3x - x = - 2

ᴏʀ , 2x = - 2

ᴏʀ , x = - 2 / 2

•°• x = - 1

ɴᴏᴡ , 

x^3 - 8 / x^3

= ( - 1 )^3 - 8 / ( - 1 )^3

= - 1 - 8 / - 3

= - 9 / - 3

= 3
