Actually welcome to the concept of the QUADRATIC EQUATION ..
Basically the Simple General form of the quadratic queation is
ax^2 -bx+ c = 0
now Basiclly we have the relation in accordance to the two roots that is the alpha and beta
such that
x^2 -( @ + ¥ ) x + (@¥)
Here , @ = alpha and ¥ = beta
so what we get is ....
always,
SUM OF THE ROOTS = -b/a = @ + ¥ .. ( since a =1 )
and ... also PRODUCT OF THE ROOTS = c/a = @¥ ...( since a =1)
