Question

What is the value of m2 -2mn+n2 for m=-2 and n=4

Answer 1

m2-2mn+n2

=4+16+16

=36

Answer 2

Answer: 36

Step-by-step explanation:

Value of m^2-2mn+n^2

By using formulae...

(a-b)^2=a^2+b^2-2ab

now,

m^2-2mn+n^2

= (m-n)^2

Here given that...

m=-2 and n=4

Therefore,

= (m-n)^2

= (-2-4)^2

= (-6)^2

= 36
