I see that it is in quadratic equation format, and my thinking is that f(x)=0 means that 0=-6x^2 + 9x +5, then I think I am supposed to multiply the -6 by the 5 and find the common factor of -30 that equals 9, but nothing does so I'm confused...Am I doing it all wrong? \n" ); document.write( "

You can put this solution on YOUR website!
You can graph it and get approximate values.
\n" ); document.write( " $\"-6x%5E2+%2B+9x+%2B+5=0\"$
\n" ); document.write( " $\"graph%28300%2C300%2C-3%2C3%2C-3%2C3%2C-6x%5E2+%2B+9x+%2B+5%29\"$
\n" ); document.write( "Looks like about $\"x=-1%2F2\"$ and $\"x=2\"$ would be approximate values.
\n" ); document.write( "For exact values you can complete the square or use the quadratic formula.
