How To Solve Algebraic Fractions – An algebraic fraction is exactly what it sounds like: a fraction where you find terms that involve algebra. It’s important to remember that the rules you learned about fractions still apply to algebraic fractions, so make sure you’re comfortable with the following topics before moving on.
This is the simplest type to simplify, requiring only the need to cancel similar conditions.
How To Solve Algebraic Fractions
Step 1: First, we need to factor the numerator and denominator of the fraction. (View factoring squares here)
Applications Of Algebraic Fractions
Step 2: Cancel our fraction, in this case we can cancel (a + 3) in both the numerator and the denominator
When adding and subtracting fractions, you must always find a common denominator, which is the same for algebraic fractions.
Now this may seem like we’ve oversimplified it, but if we consider that 2x + 4 = 2(x + 2), then suddenly we have a common factor. Get:

We need to find a common denominator between all three fractions before we can do addition and subtraction.
Since 30 is the lowest common multiple of 2, 3, and 5, we will choose 30x as the common denominator.
Now, the denominator is a special kind of quadratic expression that is denoted by the difference of two squares,

Since there is a factor of (k + 6) in both the numerator and denominator, they cancel.
Our first step when dividing fractions should be to invert the second fraction and turn the division into multiplication.
There’s a factor of one that we can cancel and also take a factor of 3 from 63 and 48,
Ways To Simplify Algebraic Fractions
Given that the denominator is (z – 1)(z + 5), we can see that there are no common factors, which means our final answer is:

Here are some videos explaining factorization and this is the main skill you will need most of the time. Like many algebra topics, it is very difficult to give specific examples because they all work together to solve many different types of questions. However, being able to simplify an algebraic fraction using factorization will help when working through higher-level problems.

Solving Equations By Multiplying Fractions
If you are asked to simplify an algebraic fraction and multiply it over or under, it is very likely that one of the factors above and below will be the same – you can use this to help you factor difficult squares!
Leaving the top and bottom of the fraction in factored form helps you see if something cancels out at the end
Mark graduated twice from the University of Oxford: once in 2009 with a first in Mathematics, then again in 2013 with a Doctorate in Mathematics (DPhil). He has nine successful years as a secondary school teacher, specializing in further maths from A-level and teaching supplementary classes for Oxbridge maths candidates. In addition to teaching, he wrote five in-house textbooks, introduced a new spiral school curriculum, and trained other math teachers through outreach programs.
