the value of c that makes the expression a perfect square binomial is c=4 .
<u>Step-by-step explanation:</u>
Here we have , an expression x2 + 4x + c or ,
. We need to find the value of c that makes the expression a perfect square binomial. Let's find out:
We have , 
⇒ 
⇒ 
Now , we know that 
Comparing above equation , to
we get ;
⇒
{
}
⇒ 
⇒ 
Therefore , the value of c that makes the expression a perfect square binomial is c=4 .
The rational root are x= 7,-3,-6
You can find them by substituting y for 0
