Question

If m=-2 and n=2; find the value of
(i) m2 + n2 - 2mn​

Answer 1

Hello!

m = - 2

n = 2

Substitute the value,

m² + n² - 2mn

= ( -1)² + 1 - 2(-1)(1)

= 1 + 1 + 2

=4

Thanks!❤

Answer 2

Answer:

Here,

m=-2 and n=2

So, m^2+n^2-2mn

(-2)^2+(2)^2-2(-2)(2)

4+4+8=16

HOPE THIS HELPS YOU❣️❣️✔️✔️✌️✌️
