# Wie rechnen Sie mit  x ^ 2-5x ?

x(x-5)

#### Erläuterung:

The first consideration is to check if there is a color(blue)"common factor"

x^2=color(red)(x)xx x" and " 5x=5xxcolor(red)(x)

"Hence there is a common factor of " color(red)(x) which can be taken out of each term.

rArrcolor(red)(x)(x-5)" is the factored form"

color(blue)"Check" by multiplying out.

rArrx(x-5)=(x xx x)-(5xx x)=x^2-5x
