[Python] Creating a quadratic equation solver inside a calculator project. My code has severe...

After taking the inputs, the code displays the equation as this:

1x^2 + -3x + 2 = 0

I want to strip the "1" and remove the "+" and replace it with a "-" sign if the input is negative

Aside from this, any other suggestions for code improvements/efficiency (both functional and formatting) will be greatly appreciated!

Thank you!

Here's the code:

#quadratic eq
if choice == '3':
print(f'\n{"Quadratic Equation Form":-^24}\n{"ax^2 + bx + c = 0":^24}\n')

a = int(input('Please enter a: '))
if a == 0 or a == '0':
print('Highest degree coefficent cannot be 0')
continue

b = int(input('Please enter b: '))

c = int(input('Please enter c: '))

#display eq
if b == 0 or 0:
quadr_eq = f'\n{f"{a}x^2 + {c} = 0":^24}'
else:
quadr_eq = f'\n{f"{a}x^2 + {b}x + {c} = 0":^24}'
print(quadr_eq)

delta = b**2 - 4*a*c

#solve formula
x1 = (-b + (delta) ** 0.5) / (2 * a)
x2 = (-b - (delta) ** 0.5) / (2 * a)

#defining discriminants
ans_string = ""

if delta > 0:
ans = [x1, x2]
ans_string += f'{"Two real and distinct solutions: " f"{ans}":^24}'

elif delta == 0:
ans = [x1]
ans_string += f'{"One real solution: " f"{ans}":^24}'

elif delta:
ans_string += f'No real solution'




solved_quadr = f'\n{"Solution":^24}\n{ans_string}\n'
print(solved_quadr)


quit_program = input('Quit program? (Y/N): ')

if quit_program.lower() == 'y':
break

solver()
