From x%5E2%2B12x%2B36 we can see that a=1, b=12, and c=36


D=b%5E2-4ac Start with the discriminant formula.


D=%2812%29%5E2-4%281%29%2836%29 Plug in a=1, b=12, and c=36


D=144-4%281%29%2836%29 Square 12 to get 144


D=144-144 Multiply 4%281%29%2836%29 to get %284%29%2836%29=144


D=0 Subtract 144 from 144 to get 0


So the discriminant is D=0


Since the discriminant is equal to zero, this means that there is one real solution.
