Trying to find the right answer to this..

121x 2 + 44xy + 4y 2 = (11x) 2 + 2(11x)(2y) + (2y) 2 = (11x + 2y) 2 [Using a 2 + 2ab + b 2 = (a + b) 2 ] = (11x + 2y)(11x + 2y) Thus, 121x 2 + 44xy + 4y 2 = (11x + 2y)(11x + 2y).

Factorise:

121x² + 44xy + 4y²

121x² + 44xy + 4y² = (11x)² + 2(11x)(2y) + (2y)²
= (11x + 2y)² [Using a² + 2ab + b² = (a + b)²]

= (11x + 2y)(11x + 2y)

Thus, 121x² + 44xy + 4y² = (11x + 2y)(11x + 2y).
