when f(x) is divided by (x-1), then what?
what do i do for this
when f(x)= x^3+ax^2+bx-15
is divided by (x-1)
when divided by (x-2) there is remainder 35
find expressions for f(1) and f(2)
THEN
set up two simutltaneoues equations and solve to find a and b
then factorise f(x) completely
what i do???????????????
