Question

i not understood plz send me​

Answer 1

Answer:

Okay first you need to pay focus and check the explanation down:)

Step-by-step explanation:

First we will separate all different variables like the variables given are:

x²-y²-1,y²-1-x²,1-x²-y²

After separation it will be:

x²-x²-x²-y²+y²-y-1-1+1

Then we will add them all or subtract

First we will solve x²

x²-x²=2x²-x²=3x²

Then we will solve y²

-y²+y²=-y²-y²=y²

Then we will solve numeric values

-1-1=-1+1=1

ANS= 3x²,y², 1

I hope you must have understood now
