(x^2 - x - 20 / x -5) / (4 / 10) @Mathematics

Answer 1

(x^2-x-20) can be factored to (x-5)(x+4)

Answer 2

Then cross out the the (x-5) in the denomanator and numerator abd you are left with:
(x-4)/(4/10)

Answer 3

Do you know abt reciprocals

Answer 4

Oh so you can cancel them out even when they arent diagonal?

Answer 5

And yes I do
