Step-by-step explanation:
Quadratic expression:-
Any equation that can be expressed in the form
where a,≠ 0 is called a quadratic equation in 'x' Here a, b ,c are called co-efficient.
Example: the quadratic expression is
here a= 1 ,b=1 and c=1
α and β are roots of the quadratic equation
sum of the two roots are α+β = -b/a = -1
product of two roots are αβ = c/a =1
There fore the product of two roots are equal to one
