**x+yz=(x+y)(x+z)**Note that this is

the

**,**

*distributive rule*So I have:

**(x + y)(x + z) = xx + xz + xy + zy**

= x + xz + xy + zy

= x(1 + z + y) zy

=x * 1 + (z + y)(zy)

= x + ((zzy + yzz)

= x +y + z?

= x + xz + xy + zy

= x(1 + z + y) zy

=x * 1 + (z + y)(zy)

= x + ((zzy + yzz)

= x +y + z?

but i need x + yz... But I don't understand what is going on in the right side
