Answer 2

REQUIRED SOLUTION:

In this question we have to apply algebraic identities to expand the given statement.

So let's start!

GIVEN:

=> (3y+2)²

TO FIND:

Expansion of (3y+2)².

SOLUTION:

(3Y+2)²=(3Y)²+(2)²+2(3Y)(2)

[∴(A+B)²=A²+B²+2(A)(B)]

=>9Y²+4+12Y

ALGEBRAIC IDENTITIES:

• (A²-B²)=(A+B)(A-B)
• (A-B)²=A²+B²-2AB
• (X+A)(X+B)=X²+(A+B)X+AB
• (A+B)²=A²+B²+2AB
