I have a quadratic equation that is x^2+6x=0, I don't know what to do because there is no "C" in the equation. Does this automatically make C 0 or is it something else
c = 0, a = 1 and b = 6.
the zeroes are at x = 0 and x = -6. you can see this by factoring:
x^2 + 6x = x(x + 6)
this is equal to zero when either
x = 0 or
(x + 6) = 0 which happens when x = -6
+12
