Exercise
$\frac{a^2}{\left(a-1\right).\left(a^2+a+1\right)}$
Step-by-step Solution
Learn how to solve simplification of algebraic fractions problems step by step online. Simplify the expression (a^2)/((a-1)(a^2+a+1)). Multiply the single term a^2+a+1 by each term of the polynomial \left(a-1\right). Multiply the single term a by each term of the polynomial \left(a^2+a+1\right). When multiplying exponents with same base you can add the exponents: a^2a. When multiplying two powers that have the same base (a), you can add the exponents.
Simplify the expression (a^2)/((a-1)(a^2+a+1))
Final answer to the exercise
$\frac{a^2}{a^{3}-1}$
