Answer 1

I think if u see it ncert pg. no. 76,77.

Answer 2

Example: try to fit x2 + 6x + 7 into x2 + 2dx + d2 + e

x^2 + (6x) + [7] matches x^2 + (2dx) + [d^2+e]

Now we can "force" an answer:

We know that 6x must end up as 2dx, so d must be 3

Next we see that 7 must become d2 + e = 9 + e, so e must be −2

And we get the same result (x+3)2 − 2 as above!
