Meaning, find the largest value for x.

x=-y%5E2-4y%2B20, a parabola opening leftward so this graph has a vertex at the right.

x=-1%28y%5E2%2B4y-20%29
x=-1%28y%5E2%2B4y%2B4-4-20%29
x=-1%28%28y%2B2%29%5E2-24%29
x=-%28y%2B2%29%5E2%2B24,
vertex (24,-2)

But instead of vertex, you might be interested in x where y=0, because one might infer you have an application problem using the word, "produced". You gave no description to say the meaning for y or for x.
