equation is in the general form of ax

Quadratic formula online calculator is the instant online tool which can easily give the solution to any

quadratic equation using this formula.

Given quadratic equation-> x

Since the quadratic equation is in the form of ax

Hence -> a= 1, b= 3, c= 2

Quadratic formula-> x = [-b ± √(b

x= [-3±√(9 -8)]/ 2

x = (-3± 1)/2

Given quadratic equation-> x

Since the quadratic equation is in the form of ax

Hence -> a= 1, b= -2, c= -15

Quadratic formula-> x = [-b ± √(b

x= [2 ± √(4 +60)]/ 2

x = (2± 8)/2
