Question

What is the possible product of (3y+5)(3y+5) using any suitable identity? ​

Answer 1

Answer:

The suitable identity for the above equation is :

$( {x}^{2} + {y}^{2} )$

Step-by-step explanation:

Proof:

A/Q,

$(3y + 5)(3y + 5) \\ = (3y + 5) ^{2} \\ = {(3y)}^{2} + 2 \times 3y \times 5 + {5}^{2} \\ = {9y}^{2} + 30y + 25$
