Value of c is 16 for which equation 
is a square of binomial !
<u>Step-by-step explanation:</u>
Here we meed to find the value of c for which equation f(x) = x^2-8x+c or , is a square of a binomial . Let's find out:
We know that
⇒ 
..........(1)
Let's simplify given equation in question
⇒
⇒ 
Comparing this equation with (1) we get :
⇒ 
⇒ 
⇒ 
Therefore , Value of c is 16 for which equation is a square of binomial !
Answer:
One solution. (x,y) = (-5,25)
Step-by-step explanation:
y = -5x
x + y = 20
x + (-5x) = 20
-4x = 20
x = -5
y = -5 (-5)
y = 25
