Given expression$=X+YZ$

Complement of that expression $=\overline{X+YZ}=\overline{X}\cdot\overline{YZ}=\overline{X}\cdot(\overline{Y}+\overline{Z})$

                                                         $=\overline{X}\cdot\overline{Y}+\overline{X}\cdot\overline{Z}$

-----------------------------------------------------------

Show that ${\color{Red}{F\cdot\overline{F}=0} }$ and ${\color{Magenta} {F+\overline{F}=1}}$

Lets make truth table for clear understanding

$F$ $\overline{F}$ $F\cdot \overline{F}$
0 1 0
1 0 0

and 

$F$ $\overline{F}$ $F+\overline{F}$
0 1 1
1 0 1
