- I am going to teach you how to solve a quadratic equation using the method of completing the square.
1. Make sure the coefficient of x^2 is positive 1.
2. Arrange them in descending order of x.
3. Open bracket then write x then half the coefficient of x then close the brackets and square the brackets.
4. Subtract the halved coefficient of x squared.
NB: YOU CAN DIVIDE BY 5 WHEN SOLVING QUADRATIC EQUATION AT 08:30 . Do not divide when you are just completing the square.
