Quadratic Equation and Roots

This lesson covers the formation of quadratic equations from given roots. It explains how to find the sum and product of the roots and demonstrates solving for unknown coefficients in a quadratic equation. Examples are provided to illustrate these concepts.

• 05:57 “with that by 2. If I do that I have beta over 2 times 2=3/8 times 2. It's clear now that your beta will be what? 3/4 so the second root is now 3/4. Now that you have it you can now go ahead to get your B. Do not forget t...”
• 05:08 “It becomes clearer. I remember very well that the value of alpha is actually -1/2 okay. If that is taken you can go ahead and substitute quite well for the value of alpha and for me I can go on substituting for the value...”
• 16:01 “this gives me alpha squared plus beta squared over alpha plus beta squared minus I can always take care of this because I know the value of my product to be 3 over 8 but I can still relax and fix it later on so in this c...”
