Write the following squares of binomials as trinomials:
(i) `((3a)/2-(5b)/4)^2`
(ii) `(a^2b-b c^2)^2`
(iii) `((2a)/(3b)+(2b)/(3a))^2 `
(iv) `(x^2-a y)^2`

Explanation

Given:

(i) `((3a)/2
-(5b)/4)^2`

Using identity,`(a-b)^2=(a^2+b^2-2ab)`

`=>(3a/2)^2+(5b/4)^2-2xx3a/2xx5b/4`

`=>(9a^2)/4+(25b^2)/16-15/4ab`

(ii) `(a^2b-b c^2)^2`

Using identity,`(a-b)^2=(a^2+b^2-2ab)`
