Question

show that (6m-5n)^ 2 -120 mn = (6m-5)^ 2​

Answer 1

Answer:

(6m-5n)^2-120mn=(6m-5)^2

12m-10n-120mn=12m-10

-10n-120mn+10=0

Answer 2

Answer:

(6m+5n)^2=36m^2+25n^2+60mn

Step-by-step explanation:

To prove this take LHS,

(6m-5n)^2+120mn=36m^2+25n^2-60mn+120mn =36m^2+25n^2+60mn

Now take RHS,

(6m+5n)^2=36m^2+25n^2+60mn

LHS=RHS,hence proved.
