Question

Show that
(4/3m-3/4n)² +2mn = 16/9m²+9/16n²

Answer 1

Answer:

L.H.S

(4/3m-3/4n)² +2/mn

= (4/3m)²+(3/4n)²-2(4/3m)(3/4n)+2/mn

=16/9m²+9/16n²-2/mn+2/mn

=16/9m²+9/16n²

=R.H.S (Prove)

L.H.S

(4/3m-3/4n)² +2/mn

= (4/3m)²+(3/4n)²-2(4/3m)(3/4n)+2/mn

=16/9m²+9/16n²-2/mn+2/mn

=16/9m²+9/16n²
