Your polynomial is in the form $\"ax%5E2%2Bbx%2Bc\"$ , where $\"a=4\"$ , $\"b=7\"$ , and $\"c=4\"$ . The discriminant is the value of the portion of the quadratic formula under the radical. The quadratic formula is: $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$ , so the discriminant is: $\"b%5E2-4ac\"$ . Just substitute the values for a, b, and c and do the arithmetic. \n" ); document.write( "
