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

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

$c = (-2)^2$

$c = 4$

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