new design without the quote looks fine.
I seem to be having a bug though/ironically am not able to solve it; I got the matrix that is F9 here https://www.dbglab.ru/en/slovar-dannykh/61/130/ (answer is 5)
My function f(x) = 5x³ + 14x² + 8x + 20 → f’(x) + x = 15x² + 28x + 8 + x = 528 is being marked incorrect.
Can you look if there is any errors in the Javascript console? Right click document → Inspect → Console (it is a horizontal tab).
