Question

Find the remainder when f(x) = 2x3 – 12x2 + 11x + 2 is divided by x – 5.

Answer 1

remainder theorem is if you sub in 5 and get a remainder of a number
then it was divided by (x-5)

so think of the (x-5) equal to zero
so it is saying
sub in 5 into the f(x) and see what you get

Answer 2

answer is your remainder

Answer 3

there are two ways u can do this... 1) divide 2) but the divisor x-5=0, which will give u x=5
Now solve for F(5) and you will get the remainder

Answer 4

Is the remainder 7?

Answer 5

well done :D
