(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I wanna show:

[tex] \langle x' - \triangle x' \vert \alpha \rangle = \langle x' \vert \alpha \rangle - \triangle x' \dfrac{\partial}{\partial x'}\langle x' \vert \alpha \rangle [/tex]

2. Relevant equations

[tex] \vert \alpha \rangle [/tex] is a state.

3. The attempt at a solution

i have no clue, can anyone give me a hint? Is the bra being splitted in to two, or what?

This is a part of eq (1.7.15) in Sakurai mordern quantum mechanics, 2ed.
