Factor some expression means to represent it as a product of several elements. Explain the above with a concrete example. Suppose we need to factor expression:
Subtract and add the term :
Factor out and find similar terms:
Add and subtract term :
Factor out and find similar terms:
Finally, factor out :
Now, we only need to factor out :
The problem of factorization often occurs in equations solving. Our online calculator based on the Wolfram Alpha system is able to factor almost any expressions.
