In my pre-calculus math class right now we are learning how to convert the standard form of a quadratic equation to general form. There are just some questions that are about filling in the missing number to make the equation, what I assume to be, a perfect square trinomial. Is that what the question is asking?
The textbook gives the answer as being 25/4. I have no idea how I would go about accomplishing that.
2) Find a number that makes the expression a perfect square of the form (x+h)^2.
e) x2 + 5x + __
I would think that I would have to find a perfect square whose root adds to 5 when multiplied by two. And I can not think of any such number.
