The problem is:
Prove this identity by algebraic manipulation:
x+yz = (x+y) * (x+z)

I am a little stuck on this problem.

I figured for the first step I could do this:
x*1 + yz
But after that, I get stuck again.

Thanks for any and all help

 

Depends what x,y and z are.

Are you talking Boolean?

Although considering the problem as Boolean is only way to satisfy the equation, you should have specified it Boolean or algebraic.

Let's start:

1) (x+y)*(x+z)
2) Taking the dual, we get xy+xz = x(y+z)
3) Taking the dual again, we get x+yz, which is what you wanted to prove.
