Question

write down the square of (mn-xy)
pls send me its ans and solution ​

Answer 1

here is the square .............

Answer 2

Answer:

(mn -xy)^2

this is in the form of

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

a=mn ; b= xy

(mn-xy)^2= (mn)^2-2mnxy+(xy)^2

therefore the answer is

(mn)^2-2mnxy + (xy)^2

m^2n^2-2mnxy+x^2y^2
