Question

simplify using identities [2y+3][2y+1]
​

Answer 1

Step-by-step explanation:

the identity is (x+a)(x+b)=x^2+(x+b)x+ab

Answer 2

Please mark this answer as brainliest.

Answer) 4y^2 - 4x + 3

The identity used here is:

(x + a)(x + b) = x^2 - (a + b)x + ab

[2y + 3][2y + 1]

= (2y)^2 - ( 3 + 1 )x + 3 x 1

= 4y^2 - 4x + 3
