How do you simplify an algebraic fraction?
To do this, look for fractions where the numerator (top number) and the denominator (bottom number) are both multiples of the same times table. This tells you their common factor, which you use to divide the top and bottom number, in order to simplify or cancel down the fraction as required.
How do you prove algebraically that a function is even or odd?
You may be asked to “determine algebraically” whether a function is even or odd. To do this, you take the function and plug –x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even.
What does it mean to prove algebraically?
An algebraic proof shows the logical arguments behind an algebraic solution. You are given a problem to solve, and sometimes its solution. If you are given the problem and its solution, then your job is to prove that the solution is right.

How to multiply algebraic fractions step by step?
When multiplying algebraic fractions, factor all numerators and denominators completely, then divide by all factors common to a numerator and denominator before multiplying.
How to add or subtract fractions step by step?
Step 1 Find the least common denominator of the two fractions. Step 2 Change each fraction to an equivalent fraction having the least common denominator. Step 3 Find the difference of the numerators and place this result over the least common denominator. Step 4 Simplify (or reduce) the fraction obtained in step 3.
Which is the factor of an algebraic fraction?
Factor the numerator and denominator of a fraction. Simplify algebraic fractions. An algebraic fraction is the indicated ratio of two algebraic expressions. In your study of arithmetic you were instructed that fractional answers were always to be left in reduced, or simplified form.
Is there a rule to add fractions in Algebra?
To add fractions there is a simple rule: (See why this works on the Common Denominator page). Subtracting fractions is very similar, except that the + is now −
