Question

Find the square of
x+2y
By using the algebraic identity

Answer 1

$\bold{\boxed{HEY!!!}}$



( x + 2y )² = ?




Identity to be used =>




( a + b )² = a² + 2ab + b²




Here a = x and. b = 2y




Using the identity




( x + 2y )² = ( x )² + 2 ( x )( 2y ) + ( 2y )²



= x² + 4xy + 4y²



(x+2y)²=x²+4xy+4y²
