QUADRATIC   FORMULA.    The roots   of  the quadratic   equation

ax  2    + bx + c   =   0   (a ≠    0)

are given   by

BINOMIAL    THEOREM.    If  n   is  a   positive    integer,    then

REMAINDER   THEOREM.    If  the polynomial  Q(x)    is  divided by  (x  −   a)  until   a

constant    remainder   R   is  obtained,   then    R   =   Q(a).   In  particular, if  a   is  a

root    of  Q(x)    =   0,  then    Q(a)    =   0.
