Is this 2x%5E2+=+5x+%2B+8+-+9x+%2B+x?
...
2x%5E2+=+-3x+%2B+8
...
2x%5E2+%2B+3x+-+8+=+0
...
Using the quadratic equation
x+=+%28-3+%2B-+sqrt%283%5E2-4%282%29%28-8%29%29%29%2F%282%282%29%29
...
x+=+%28-3+%2B-+sqrt%289%2B64%29%29%2F4
...
x+=+%28-3+%2B-+sqrt%2873%29%29%2F4
...
x+=+%28-3+%2B+sqrt%2873%29%29%2F4
AND
x+=+%28-3+-+sqrt%2873%29%29%2F4
