Move constant to other side
add 1
4c^2-8c=1
divide by 4 to make leading coeficient 1
c^2-2c=1/4
take 1/2 of linear coeficient and square it
-2/2=-1, (-1)^2=1
add that to both sides 
c^2-2c+1=1/4+1
factor perfect squaer and add
(c-1)^2=5/4
square root both sides
c-1=+/-(√5)/2
add 1
c=1+/-(√5)/2
c=2.12 or -0.12

Answer:
x = 10
Step-by-step explanation:
In the last step, you can see that the fraction  has been multiplied by its reciprocal
 has been multiplied by its reciprocal  , making it cancel out. The reciprocal has been multiplied to both sides, so all you need to do is multiply
, making it cancel out. The reciprocal has been multiplied to both sides, so all you need to do is multiply  ·
 ·  :
 :
6 · 5 = 30
3 · 1 = 3
<u><em>So now you should have the fraction:</em></u>
x = 
<u><em>But, you can still simplify the fraction by dividing 30 by 3:</em></u>
x = 10
