Question

Write f(x)=x^3-3x^2-3x-32 in the form of f(x)=(x-k)q(x)+r when k =5

Answer 1

(x-5)(x^2 + 2x + 7 ) + 3 .... u just need to diveide the eqn with x-5

Answer 2

so g(x) = x^2 +2x +7 and r = 3

Answer 3

is it clear!???

Answer 4

I still don't understand. How do I get from x^3 -3x^2 -3x -32 to what you have.

Answer 5

so u know how to divide quad eqn??
