A³-1= (A -1) (A² +A +1)
Step-by-step explanation:
As per Algebra, a³ - b³ = (a -b) (a² +b² +ab)
Let's apply that a = A and b = 1 in the above equation.
So assuming A³-1 is the same as A³-1³, we can expand this equation as (A - 1) (A² + 1² + (A*1))
Rearranging we get, A³-1= (A -1) (A² +A +1)
So the factor in the blank will be (A - 1)
