"5.4 Synthetic Division
Only the numbers are used, no variables
           Synthetic Division is
dividing a polynomial by a binomial
(2x2 -1x-3) ÷ (x+1)
(2x2-1x-3) ÷ (x+1)
The x value
that cancels
the divisor (-1)
is the multiplier
The answer
(quotient):
   2x - 3
(2x2-1x-3) ÷ (x+1)

#
remainder
The
quotient
is:
(3x3+5x2-2x-120) ÷ (x-3)
 3x3+14x2+40x
 3x2+14x+40

Quotient:
(5x3-6x2+3x+14) ÷(x+1)
 5x2-11x+14
 5x3-11x2+14x
The degree (highest power) of the quotient
is ALWAYS one lower than the degree of the dividend
