Given :-

(6x + 5y)² = 36x² + .......... + 25y²

To Find :-

Value of ..........

Solution :-

We know that,

$\large{\underline{\boxed{\green{\sf{(a + b) ^2 = a^2 + 2ab + b^2}}}}}$

__________[Put Values]

$\sf{(6x + 5y)^{2} = 36 {x}^{2} + ...... + 25 {y}^{2} } \\ \\ \sf{ \cancel36 {x}^{2} + 60xy + \cancel 25 {y}^{2} = \cancel 36 {x}^{2} + ......... + \cancel25 {y}^{2} } \\ \\ \sf{60xy = ......}$

$\huge{\underline{\boxed{\blue{\sf{60xy = .....}}}}}$
