Solve by using the quadratic formula.
\n" ); document.write( "3x^2=11x+4
\n" ); document.write( "3X^2-11X-4=0.....COMPARING WITH ..AX^2+BX+C=0....
\n" ); document.write( "A=3........B=-11.....C=-4\r
\n" ); document.write( "\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( " $\"x+=+%2811+%2B-+sqrt%28+%28-11%29%5E2-4%2A3%2A%28-4%29+%29%29%2F%282%2A3%29+\"$
\n" ); document.write( " $\"x+=+%2811+%2B-+sqrt%28+121%2B48+%29%29%2F%286%29+\"$
\n" ); document.write( " $\"x+=+%2811+%2B-+sqrt%28+169+%29%29%2F%286%29+\"$
\n" ); document.write( "X=(11+13)/6=4......OR
\n" ); document.write( "X=(11-13)/6=-2/6=-1/3 \n" ); document.write( "
