Beyond the Answer
To simplify the first expression, we can rewrite
as
and
as
. This allows us to factor the expression adequately. The complete factorization would reveal either common terms or a pattern. In the second expression, converting
into a fraction gives us
, which can also present opportunities for factoring in relation to powers of
.
When approaching problems like these, be alert for opportunities to apply algebraic identities, such as the sum of cubes or squares, and remember to check the degrees of polynomials — sometimes, the highest power gives farewell clues to simplifying expressions. Common mistakes include overlooking the properties of exponents, so a double-check of exponent rules can save you from unnecessary errors!
