X^2-4x+c find the value of c
Sonbull [250]

Answer:

c = 4

Step-by-step explanation:

Given

x^2 - 4x + c

Required

Find c

The question is incomplete. However, I'll assume the expression is a perfect square.

To find c, we make use of the following formula

c = (\frac{b}{2})^2

Where

ax^2 + bx + c

By comparison with x^2 - 4x + c

a =1

b = -4

So, c = (\frac{b}{2})^2 becomes

c = (\frac{-4}{2})^2

c = (-2)^2

c = 4

<em>The value of c that makes the expression, </em>x^2 - 4x + c<em> a perfect square is 4 and the expression is: </em>x^2 - 4x + 4<em></em>

The area of this square
ANEK [815]

It appears as if 12cm is half the length of the side so we can assume that the total length of one side is 24cm.


The area of a square is given by the equation A=s^{2} where s is the length of the side.  

A=24^{2}

A=576


The area of this square is 576cm2.


Hope this helps!
