Step-by-step explanation:
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 .
Depends.
A. -12 - -6 = -6
but
B. -6 - -12 = 6
Two negatives always cancel, so the equation for A. would be like saying
-12+6, and B. -6+12.
