Question

find the sum of p square ,-q square ,q square,-r square,r square,-p square​

Answer 1

Answer:there can be two answers of this question as you have not mentioned the condition. So , if p²-q²+q²-r²+r²-p² then its is equal to 0.

But if p²+(-q²)+q²+(-r²)+r²+(-p²) then it is equal to 2(p²+q²+r²).

Step-by-step explanation:

So, taking first condition.

If p²-q²+q²-r²+r²-p² then

p² and -p² will cancel each other and

q² and -q² will cancel each other and

r² and -r² will cancel each other.

Hence, the answer will be equal to zero(0).

Now, taking 2nd condition i.e., if

p²+(-q²)+q²+(-r²)+r²+(-p²) then

=p²+q²+q²+r²+r²+p²

=2p²+2q²+2r²

=2(p²+q²+r²)

Hence, the answer will be 2(p²+q²+r²).
