# Find the conjugate of each of the following: Given: Firstly, we calculate and then find its conjugate [ (a + b)2 = a2 + b2 + 2ab] [ i2 = -1] Now, we rationalize the above by multiplying and divide by the conjugate of 3 – i  …(i)

Now, we know that,

(a + b)(a – b) = (a2 – b2)

So, eq. (i) become   [ i2 = -1] [ i2 = -1]    Hence, So, the conjugate of is Rate this question :
