a(x-1)(x-m)求导a(x-1)(x-m)求导a(x-1)(x-m)求导a(x-1)(x-m)求导a(x-1)(x-m)求导a(x-1)(x-m)求导[a(x-1)(x-m)]''=a(x-1)''

a(x-1)(x-m)求导 a(x-1)(x-m)求导
a(x-1)(x-m)求导
a(x-1)(x-m)求导

a(x-1)(x-m)求导 a(x-1)(x-m)求导
[a(x-1)(x-m)]'
=a(x-1)'*(x-m)+a(x-1)(x-m)'
=a(x-m)+a(x-1)
=a(2x-m-1)

f(x)=a(x-1)(x-m)
=a(x^2-(1+m)x+m)
=ax^2-a(1+m)x+am

f'(x)=2ax-a-am
