Answer 2

225/4

Explanation:

When you are trying to find the number to be added to a binomial of the form :
`x^2+bx` in order to make it a perfect square trinomial, all you need to do is to use the square of half of the coefficient b. That is :
`((b)/(2) )^2`.

In your case this is:
`((15)/(2) )^2=(15^2)/(2^2)=(225)/(4)`
