Come consideri # x ^ 2-5x #?
Risposta:
#x(x-5)#
Spiegazione:
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#
