Question

How do you simplify `(x^2 + 2x)/(5x+10)`?

Answer 1

We can factor out of numerator and denominator what's multiplying both terms on each part of the fraction:

`(x(x+2))/(5(x+2))`

Now, we can cancel what's both on numerator and denominator, as when a number/equation divides itself, the result is `1`.

`(xcancel((x+2)))/(5cancel((x+2)))=color(Green)(x/5)`
