There is Product rule calc ab that can make the technique much easier.
But there's one thing I'm not happy about, that is, you take away the function to get answer right after the question show on screen, now I have to take a picture of it.

THANK YOU WHO EVER INVENTED THIS APP, limited ads as well, just don't depend on it too much, the tests and quizes require your mind to understand the problems, it teaches you how to do the equations as well, which is amazing.

I suggest it, it's worse than Microsoft maths in the camera sense because you can't make the square as big, but it's better than Mm because it always shows steps on how to solve the equation, explore the app a bit and you will understand.
