We're gonna solve x squared
plus 12 x plus 36 equals zero
using our quadratic formula.
So, a will be one, b will be 12,
and c will be 36.
So, we'll have negative 12 plus
or minus the square root of 12 squared
minus four times one times 36.
All of that over two times one.
That'll turn into
negative 12 plus or minus,
we end up getting zero
inside the square root.
So, plus or minus the square
root of zero over two.
So, since plus zero and minus
zero are the same thing,
we'll just get one answer here.
So, negative 12 divided by
two gives us negative six.
