Answer 2

Answer:

question:-

use a suitable identity to get each of the following products (3x+5y)²

solution:-

• 9x²+30xy+25y²

$\orange{let's\:find\: out\:!!}$

by using identity I

using identity :-

(a+b)² = a² + 2(a)(b) + b²

working with question :-

=>> (3x + 5y)² = 3x² + 2(3x)(5y) + 5y²

==> (3x+5y)² = 9x² + 30xy + 25y²

hence the product of (3x+5y)² is 9x² + 30xy + 45y²
