Question

find suitable identity to find the products (2y+5) (2y+5)​

Answer 1

Answer:

we can use the identity (a+b)^2

(2y+5)^2

(a+b)^2=a^2 +  b^2+2ab$=(2y+5)^{2} \\=(2y)^2+(5)^2+2*2y*5\\=4y^2+25+20y$

hope it helps u

Step-by-step explanation:

Answer 2

Answer:

4y^2 + 25 +20 y

Step-by-step explanation:

(2y+5)(2y+5)

1. (2y+5)^2. (a+b)^2=a^2+b^2+2ab

(2y)^2 + 5^2 +2*2y*5

4y^2 + 25 +20 y ans
