Regarding the remainder theorem is this correct:

f(x) = divisor x quotient + (remainder / divisor)

If you divide by the divisor, the "remainder" part isnt correct. Its just like normal division so
7 = 2*3 + 1
dividend = divisor x quotient + remainder
or
7/3 = 2 + 1/3
dividend / divisor = quotient + remainder / divisor

Right thanks a lot

if you divide x2 + 2x + 7 by x - 3 you get x + 5 with remainder 22

so

x2 + 2x + 7 = (x - 3)(x + 5) + 22
