Answer 2

${\huge{\underline{\boxed{\red{\mathcal{Answer}}}}}}$

$\implies (5x - 7y)^2 \\ \text{We know that, (a-b)^2 = a^2 + b^2 - 2ab } \\ \text{Here, a = 5x and b = 7y. So, } \\ \implies (5x - 7y)^2 = (5x)^2 + (7y)^2 - 2*(5x)*(7y) \\ \implies (5x - 7y)^2 = 25x^2 + 49y^2 - 70xy. \\ \text{HOPE IT HELPS!!!}$

Formula Used:

• $(a-b)^2 = a^2 + b^2 - 2ab$
