How can you tell without doing division if a number is a multiple of 3?

you add the numbers up and if they are a multiple of 3 it can be divided by 3

6 is a multiple

455

4 + 5 + 5 = 14

14 is not a multiple

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
