Determine the value of K that would make this expression a perfect square
Mumz [18]

Answer: k=9/4

Step-by-step explanation: We can do this by finding a number that adds up to 3 when multiplied by 2. The best way to do this is to use ((b^2)/4) which can usually find you the number for a perfect square based on b, which we have. So, 3^2 / 4 =9/4, meaning k=9/4. We can check:

>x^2 +3x +9/4

> (x+3/2)(x+3/2)

Perfect square.
