Question

Divide: (x^3-20x+16)÷(x-4)

Answer 1

Hi

x³ - 20x + 16 / x -4

In this case you need to factorize first

(x-4)(x²+4x-4) / (x-4)

Now there are two common factors so you just need to eliminate them. So now we only have

x² + 4x -4

That's the answer :)

I hope that's help:) Any question ?
