Question

Boolean algebra: Factor to obtain a product of sums (answer should have 3 terms):

WXY + WX'Y + WYZ + XYZ'

Please walk me through it? Show me which rules you apply?

Answer 1

\[ \large WXY+WX'Y+WYZ+XYZ'= \]
\[ \large =WY(X+X')+WYZ+XYZ' \]
\[ \large =WY1+WYZ+XYZ' \]
\[ \large =WY(1+Z)+XYZ'=WY1+XYZ'=WY+XYZ' \]
