# Python program to Quadratic Equations with Solutions at Specified Range of Coefficient

 ```import math x1 = int(input("Insert the value of x1: ")) x2 = int(input("Insert the value of x2: ")) y1 = int(input("Insert the value of y1: ")) y2 = int(input("Insert the value of y2: ")) z1 = int(input("Insert the value of z1: ")) z2 = int(input("Insert the value of z2: ")) x = range(x1, x2+1) y = range(y1, y2+1) z = range(z1, z2+1) for i in x: if i == 0: continue for j in y: for k in z: print(i, j, k, end=' ') A = j*j-4*i*k if A >= 0: x1 = (-j - math.sqrt(A))/(2*i) x2 = (-j + math.sqrt(A))/(2*i) print("Valid", round(x1,2), round(x2,2)) else: print("Invalid")```

Output:
