Write the following squares of binomials...

Write the following squares of binomials as trinomials:
(i) `(x+2)^2`
(ii) `(8a+3b)^2`
(iii)`(2m+1)^2`
(iv) `(9a+1/6)^2`

Text Solution

Verified by Experts

Given:
`(i) (x+2)^2`
Using identity:
`(a+b)^2=a^2+b^2+2ab`
`=> (x^2+2^2+2xx(x)xx2)`
`=> (x^2+4+4x)`
(ii) `(8a+3b)^2`
Using identity:
...
