Question

P= -2, q= -1 and r = 3. find the value of
(ii) 2psquare - square + 3rsquare​

Answer 1

Answer:

Given,

P= -2, q= -1 and r = 3

then value of 2psquare -q square + 3rsquare​

=2(-2)square-(-1)square+3(3)square

=2(4)-1+27

=8-1+27=34 answer.

Answer 2

Answer:

we have , p =-2

q = -1

r = 3

we want to find the value of

2p^2 - (-1)^2 +3r^2

Now putting the values

2(-2)^2 -(-1)^2 +3r ^2

= 2(4) - (1) + 3(9)

= 8. - 1 + 27

=34 ANS
