$\"2x%5E2%2B3x-7=0\"$
\n" ); document.write( "I would use the quadratic formula
\n" ); document.write( "a = 2
\n" ); document.write( "b = 3
\n" ); document.write( "c = -7
\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( " $\"x+=+%28-3+%2B-+sqrt%28+3%5E2-4%2A2%2A%28-7%29+%29%29%2F%282%2A2%29+\"$
\n" ); document.write( " $\"x+=+%28-3+%2B-+sqrt%2865%29%29%2F4+\"$
\n" ); document.write( "You can always check answer by plugging one of the two
\n" ); document.write( "solutions back into equation
\n" ); document.write( " $\"2%2A%28%28-3+%2B+sqrt%2865%29%29%2F4%29+%5E2%2B3%2A%28%28-3+%2B+sqrt%2865%29%29%2F4%29-7=0\"$
