Answer 2

Answer:

225/4

Step-by-step 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 : $(\frac{b}{2} )^2$.

In your case this is: $(\frac{15}{2} )^2=\frac{15^2}{2^2}=\frac{225}{4}$
