Question

mx - ny = m2 + n2
x + y = 2m​

Answer 1

Answer:

mx-ny =m2+n2=mx-ny =m2+n2+2mn-2mn=

Step-by-step explanation:

mx-ny =(m+n)^2-2mn mx -ny =m2+n2x+y=2m,,,,(1)

,x+y=2m,,,,,,,(2) substituteing (2)in(1) =mx-ny =(m+n) ^2-(x+y) n = (m+n) 2+nx-ny adding ny to both sides you get mx=(m+n)^2-nx=mx+nx=(m+n)^2=x(m+n)=y=m+n
