I want this to become this
I searched a lot, but I couldn’t find it. Just tell me the name of the function. It’s enough
1
(5y-3x)**2
to:
25y-30xy+9x*2
How?
please help me!
I tested with factor() and it didn’t work !
>Solution :
expand()
>>> expand((x + 1)**2)
2
x + 2⋅x + 1
>>> expand((x + 2)*(x - 3))
2
x - x - 6
