I'm currently learning about boolean expressions. Currently, we're looking at how to simplify them. For this question I need to show the intermediate steps using the laws of boolean algebra. 

However, I'm not sure where to start with this one (overline is negation):

$A\overline{B} + \overline{B}C + AB\overline{C}$  

needs to be simplified to  

$\overline{B}C + A\overline{C}$

Can anyone help me out? Thank you!
