2 +bα+c=0
Some other points to remember
• The root of the quadratic equation is the zeroes of the polynomial p(x).
• We know from chapter two that a polynomial of degree can have max two zeroes. So a quadratic equation can have maximum two roots
• A quadratic  equation has no real roots if b2- 4ac < 0
