Have no clue what it s all about

D = A(B+C) – 2AC/B + C2

PUSH A=TOP OF STACK

PUSH B= TOP OF STACK

PUSH C =TOP OF STACK

MUL TOP=A(B+C)……………….A(B+C)

MUL TOP=2A*C………………………... 2AC

MUL TOP=C*C………………...C2 C SQUARE

DIV TOP=2AC/B+(C*C)

SUB TOP=(A(B+C) – 2AC ) )

DIV TOP=(A(B+C) – 2AC ) ) /B+(C*C)

 POP D M[D] = TOP

A:

B:

C:
