determine nature of roots

Without solving the quadratic equation, the nature of the roots can be determined using the discriminant. i) D >0 i.e., positive and not a perfect square. The roots are real and distinct (irrational). ii) D >0 i.e., perfect square. The root..

Determine the nature of roots of the equation ( a 2 + b 2 ) x 2 - 2 b ( a+c ) x + ( b 2 + c 2 ) = 0 if a , b , c are in GP. => Negative and distinct or Positive and distinct or Imaginary or Real and equal..

Sound is a form of energy. It is produced by the vibration of particles and it travels in a wave-like motion. The number of waves passing a point per second is called the frequency and its unit is Hertz (Hz). The pitch of the sound (high or low sounding) is measured by the frequency. Man can hear ..
