Answer 1

Answer:

a( a - 1 )

Step-by-step explanation:

a² - a = a × a - a

Taking out a as common,

= a( a - 1 )

Answer 2

formula for equations

A “formula” is generally a equation of form y=f(a, b, c) given for the purpose of calculating the value of the dependent variable (y in this case) given the values of the independent variables (a, b, and c in this case).

hope its help u.

a² - a = ?

= a^2 - a= 0

= a(a-1) = 0

= a= 0

= a = 1
