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:
yes, 1 can never equal 2 unless it is manipulated (ex: 1(2) = 2)
because one is not being manipulated to equal 2 here, it is a false statement and will always be a false statement.
Rounding 2 SF would give you 19
Answer:
x=-7.5
Step-by-step explanation:
3x-2/4=2x-8
-2x -2x
x-2/4=-8
+2/4 +2/4
Put separate terms on each side
x=-7.5
Please correct me if I'm wrong
Hope this helps!
