Question

Quadratic Formula

Can anyone explain the steps to this problem.. the only thing I need to ask is where does the "C" go if there is no C?

Answer 1

2x^2-6=0

Answer 2

if there is no C don't use the formula
ok in your example there is no b

Answer 3

much easier to write
\[2x^2=6\\
x^2=3\\
x=\pm\sqrt3\] and be done
no formula necessary

Answer 4

Oh I see. Thanks so much! ;P

Answer 5

Answer 6

Another question real quick.. If the problem were related someway to this one.. would I still have to leave it as it is? Just making sure.
