Question

Which of the following constants can be added to x2 - 3x to form a perfect square trinomial?

1
2

Answer 1

You want the form:
\[a^2-2ab+b^2\]and in your case \[a=x\]and \[-2ab=-3x\]

Answer 2

Since, a=x; you know that -2b=-3, or \[b=\frac{3}{2}\]

Answer 3

And you need to add \[b^2=\frac{9}{4}\]
