part a: $\"3x%5E2-7x-5=0\"$
\n" ); document.write( "using the quadratic, we get
\n" ); document.write( " $\"x+=+%287+%2B-+sqrt%28+49-4%2A3%2A%28-5%29+%29%29%2F%286%29+\"$
\n" ); document.write( "simplifying, we get
\n" ); document.write( " $\"x+=+%287+%2B-+sqrt%28+109+%29%29%2F%286%29+\"$
\n" ); document.write( "--
\n" ); document.write( "part b: x-intercept is
\n" ); document.write( " $\"x+=+%287+%2B-+sqrt%28+109+%29%29%2F%286%29+\"$
\n" ); document.write( "or x ~ -.573 ; x ~ 2.907 \n" ); document.write( "
