You can put this solution on YOUR website!
y=-5x^2 is easy!
You need to set "y" to zero (0)and you also need to know that you're adding zeros(0) to it:
0=-5x^2+0+0
Now you do the quadratic formula:
x=%28-b%2B-sqrt%28b%5E2-4%2Aa%2Ac%29%29%2F%282%2Aa%29
Then substitue by pluging in numbers with the letters(ax^2+bx+c)
And simplify:
x=-0%2B-sqrt%280%29%29%2F%28-10%29
And this is your answer. Some answers are usually radicals.
