Write a python code in finding the roots of a quadratic equation?

Can someone help with this...I am not getting the desired output. Also apart from string commands, is there any other way to remove the brackets from the output? import cmath a=int(input()) b=int(input()) c=int(input()) d = (b**2) - (4*a*c) x = (-b-cmath.sqrt(d))/(2*a) y = (-b+cmath.sqrt(d))/(2*a) r1=str(x) q1=r1[1:6] r2=str(y) q2=r2[1:6] print("output is %s and %s" %(q1, q2))

hey what exactly do you need why are you slicing ? cmath.sqrt returns a complex number so it is in brackets .. if you want real & imaginary parts try this x.real ,y.imag props of complex numbers And I do this way a=int(input()) b=int(input()) c=int(input()) dRoot = ((b**2) - (4*a*c))**(1/2) x = (-b-dRoot)/(2*a) y = (-b+dRoot)/(2*a) print('Roots of {}x**2+({})x+({}) are {},{}'.format(a,b,c,round(x,4),round(y,4)))
