Question

if X=-2/3,y=1/4 ,and z=-5/4, then verify y (z-x) = yz - zx
who gives ans I will mark as brainliast and thanks and vote the proper ans it's my promise​

Answer 1

I think the question might be wrong..

I have the explanation:

Let us assume that x=3,y=2 and z=1.

Given,

y(z-x)=yz-zx.

2 ( 1 - 3 ) = ( 2 × 1 ) - ( 1 × 3 )

2 (-2) = 2-3

-4 = -1

But , -4 is not equal to -1.

Here,LHS is not equal to RHS.

That means , y ( z - x ) is not equal to yz - zx.

So,that means the given question is wrong.

If we have to make a correction in the question,we should do it in RHS that is it should not be yz - xz.Maybe it should be yz - yx.

If you feel the same , please follow me friends..

Thank you
