Question

pq -q² + r², if p=1,q=2 and r=-3 please tell me fast​

Answer 1

Answer:

p = 1

q = 2

r = 3

So, pq - q^2 + r^2 = 2 - 4 + 9

= 11+4 = 7

Hope it Helps :)

Answer 2

7

Step-by-step explanation:

Given -

Find the value of pq - q² + r², if p = 1, q = 2 and r = 3

Solution -

pq - q² + r²

[put the value of p, q and r]

=> (1 × 2) - (2)² + (3)²

=> 2 - 4 + 9

=> 2 + 9 - 4

=> 11 - 4

=> 7

Hence the value of pq - q² + r² = 7.

hope it helps.
