Answer:
(4m+5n)2+(5m+4n)2-(4m+5n)(4m-5n)
8m+10n+10m+8n-(4m^2-5n^2)
(a+b ) (a-b)= a^2-b^2
8m+10m+8n+10n-16m^2+25n^2
18m+18n-16m^2+25n^2
18m-16m^2+25n^2+18n ans
so it will help you

(4m+5n)²+(5m+4n)²-(4m+5n)(4m-5n)
= 16m²+25n²+40mn+25m²+16n²+40mn-(16m²-25n²)
= 16m²+25n²+40mn+25m²+16n²+40mn-16m²+25n²
=25n²+40mn+25m²+16n²+40mn+25n²
= 66n² +25m²+80mn
