Answer 1

a =5
b =15
c =-50
começo=-b
b2=b**2
meio=(b2-4*a*c)**(1/2)
final=2*a
x1=(começo+meio)/final
x2=(começo-meio)/final
print("x1 es igual a "+str(x1))

Answer 2

You cant concat numbers with strings. So make the numbers a string by str() method.
eg: print("x1="+str(x1))

Answer 3

So, it comes out to be that in python, you cannot concatenate a string with a float. To solve this problem, you first need to convert x1 into a string.

Answer 4

how would I write it?
