I know factor theorem. If the remainder when dividing P(x) by D(x) is zero, then D(x) is a factor of P(x). P(x) is any polynomial D(x) is the divisor being a factor means it is included in multiplying.

is that correct? could you improve my definition of factor ?

your 2 number question simply means that if u divide P(x) by (x+3) then remainder is zero. dw:1343209619170:dw
