If `25x^(2)-40xy+16y^(2)=a^(2)` then `a=`

9x^(2)+24xy+16y^(2)

25x^(2)+36y^(2)+60xy

(a) Factorise : 9x^(2) - 24 xy + 16y^(2) (b) Factorise : 25x^(2) + (1)/(25x^(2)) + 2

Factorise :25x^(2)-30xy+9y^(2)

Factories 25 x ^(2) + 16 y ^(2) + 4z ^(2) - 40 xy + 16 xy - 20xy

Factories (i) 25 x ^(2) + 16 y ^(2) + 4z ^(2) - 40 xy + 16 xy - 20xy (ii) 9a ^(2) + 4b ^(2) + 16 c ^(2) + 12 ab - 16 bc - 24 ca
