What do you want to do with this equation?
2x%5E3%2B6x%5E2%2B3x%2B9 Factor it??
%282x%5E2%2B3%29%28x%2B3%29
You can't solve for it x until you set the equation equal to something, like zero for example.
2x%5E3%2B6x%5E2%2B3x%2B9+=+0 Solve it factoring,
2x%5E2%2B3%29%28x%2B3%29+=+0 Apply the zero product rule.
2x%5E2%2B3+=+0 or
x%2B3+=+0 then...
2x%5E2+=+-3--->x%5E2+=+-3%2F2--->highlight%28x+=+sqrt%28-3%2F2%29%29 or highlight%28x+=+-sqrt%28-3%2F2%29%29
highlight%28x+=+-3%29 or highlight%28x+=+3%29
