The first thing about the Quadratic Formula
is what we are actually doing, the first thing
part is how do we find the quadratic function
a x squared plus b x plus c we have a quadratic
function set equal to zero we're using the
quadratic function negative b plus or minus
the square root b squared minus 4 a c all
over 2 a to find where the function crosses
the x-axis or when the function is equal to
zero so there is a tune that pretty much everyone
knows by One Direction that we will use for
to memorize this formula you are welcome to
sing along if you know the tune get out get
out get out of my head fall into my arms instead
i don't i don't know what it is but I need
that one thing, you got that one thing! good
so if you use that same chorus we can sing
the quadratic formula that is right here behind
me negative b plus or minus the square root
of b squared minus 4 a c all over 2 a now
you know the quadratic formula now you know
the quadratic formula so that is how it goes
lets do it one more time just so you have
it down and i hope you enjoyed it negative
b plus or minus the square root of b squared
minus 4 a c all over 2 a now you know the
quadratic formula, now you know the quadratic
formula thank you for Watching!
