# Find the Following Squares by Suing the Identities. (2by3 M + 3by4 N)Square2 - Mathematics

Find the following squares by suing the identities.

(2/3 m + 3/4 n)^2

#### Solution

(2/3 m + 3/4 n)^2 = (2/3 m)^2 + 2(2/3 m)(3/2 n)+ (3/2 n)^2  [(a + b)2 = a2 + 2ab + b2]

= 4/9 m^2 + 2mn + 9/4 n^2

Is there an error in this question or solution?
