$$\left(a \wedge b\right) \vee \left(c \wedge d\right) = \left(a \vee c\right) \wedge \left(a \vee d\right) \wedge \left(b \vee c\right) \wedge \left(b \vee d\right)$$
$$\neg \left(\left(a \wedge b\right) \vee \left(c \wedge d\right)\right) = \left(\neg a \wedge \neg c\right) \vee \left(\neg a \wedge \neg d\right) \vee \left(\neg b \wedge \neg c\right) \vee \left(\neg b \wedge \neg d\right)$$
$$c \wedge d \wedge \neg \left(\left(a \wedge b\right) \vee \left(c \wedge d\right)\right) = \text{False}$$
$$\neg \left(c \wedge d \wedge \neg \left(\left(a \wedge b\right) \vee \left(c \wedge d\right)\right)\right) = 1$$
$$\neg b \wedge \neg \left(c \wedge d \wedge \neg \left(\left(a \wedge b\right) \vee \left(c \wedge d\right)\right)\right) = \neg b$$
$$\neg \left(\neg b \wedge \neg \left(c \wedge d \wedge \neg \left(\left(a \wedge b\right) \vee \left(c \wedge d\right)\right)\right)\right) = b$$
