P^2 Q^2 +pq−q^3 −p^3
Introduction
In algebra, simplifying complex expressions is a crucial skill that helps in solving equations and inequalities. The given expression, p^2 q^2 + pq − q^3 − p^3, appears to be a combination of various terms involving powers of p and q. In this article, we will simplify this expression step by step, using various algebraic techniques.
Step 1: Factor out Common Terms
The first step in simplifying the expression is to look for common terms that can be factored out. In this case, we can factor out p^2 and q^2 from the first two terms, and p and q from the last two terms.
p^2 q^2 + pq − q^3 − p^3 = (p^2 q^2 + pq) - (q^3 + p^3)
Step 2: Factor out p and q
Now, we can factor out p and q from the first two terms and the last two terms, respectively.
(p^2 q^2 + pq) - (q^3 + p^3) = pq(pq + 1) - q(pq + 1)
Step 3: Factor out (pq + 1)
We can now factor out (pq + 1) from both terms.
pq(pq + 1) - q(pq + 1) = (pq + 1)(pq - q)
Step 4: Simplify the Expression
Now, we can simplify the expression by combining like terms.
(pq + 1)(pq - q) = pq^2 - q^2 + pq - q
Step 5: Factor out q
We can now factor out q from the first two terms and the last two terms, respectively.
pq^2 - q^2 + pq - q = q(pq - q) + (pq - q)
Step 6: Factor out (pq - q)
We can now factor out (pq - q) from both terms.
q(pq - q) + (pq - q) = (pq - q)(q + 1)
Conclusion
In conclusion, the simplified expression is (pq - q)(q + 1). This expression can be further simplified by factoring out q from the first term.
(pq - q)(q + 1) = q(p - 1)(q + 1)
Final Answer
The final answer is q(p - 1)(q + 1).
