Which of the following constants can be added to x^2- 3x to form a perfect square trinomlal?
creativ13 [48]

Answer:

A 21/4

Step-by-step explanation:

When forming a perfect square trinomial you need to "complete the square".

All of the steps to completing the square when solving an equation:

1.  The leading coefficient must be 1.  

2.  Divide b by 2.

3.  Square (b/2)

4.  Add (b/2)^2 to both sides to keep the polynomial balanced.

5.  You can now write the perfect square trinomial and solve.

x^2 - 3x  

-3/2

(-3/2)^2 = 9/4 = 2 1/4

So Katie gave half of her pencils to Maggie.(1/2x)

So Maggie keeps five pencils and give the rest to Jamil.

So

X/2 = 5 + y

Where y is the number of pencils given to Jamil and 5 is the one kept by Maggie.

Y=( x/2 )- 5
