Question

Find the square of (2y+3) ie (2y+3)^2

Answer 1

Answer:

(4y+9) (16y+81) is the right answer

Answer 2

Answer:

4y^2 + 12y + 3

Step-by-step explanation:

We know,

(a+b)^2=a^2 + 2×a×b + b^2

Therefore, (2y+3)^2

=(2y)^2 + (2×2y×3) + (3)^2

=4(y)^2 + 12y + 9

Please note that it is 4(y)^2 and not (4y)^2.

Hope it helps! ^-^
