8x+%2B+3x%5E2+-+2000
Thats a quadratic equation. You can factor it or use the quadratic formula
To find the zeros ...
8x+%2B+3x%5E2+-+2000
3x%5E2+%2B+8x+-+2000+=+0
Solved by pluggable solver: SOLVE quadratic equation with variable
Quadratic equation ax%5E2%2Bbx%2Bc=0 (in our case 3x%5E2%2B8x%2B-2000+=+0) has the following solutons:

x%5B12%5D+=+%28b%2B-sqrt%28+b%5E2-4ac+%29%29%2F2%5Ca

For these solutions to exist, the discriminant b%5E2-4ac should not be a negative number.

First, we need to compute the discriminant b%5E2-4ac: b%5E2-4ac=%288%29%5E2-4%2A3%2A-2000=24064.

Discriminant d=24064 is greater than zero. That means that there are two solutions: +x%5B12%5D+=+%28-8%2B-sqrt%28+24064+%29%29%2F2%5Ca.

x%5B1%5D+=+%28-%288%29%2Bsqrt%28+24064+%29%29%2F2%5C3+=+24.5209592395538
x%5B2%5D+=+%28-%288%29-sqrt%28+24064+%29%29%2F2%5C3+=+-27.1876259062204

Quadratic expression 3x%5E2%2B8x%2B-2000 can be factored:
3x%5E2%2B8x%2B-2000+=+3%28x-24.5209592395538%29%2A%28x--27.1876259062204%29
Again, the answer is: 24.5209592395538, -27.1876259062204. Here's your graph:
graph%28+500%2C+500%2C+-10%2C+10%2C+-20%2C+20%2C+3%2Ax%5E2%2B8%2Ax%2B-2000+%29

That's not a question, so there's no answer.

It's not an equation, there's no equal sign.
