Algebraic Fractions
Gbogbo ọrọ náà
An algebraic fraction is just a fraction with algebra in it, and it obeys exactly the same rules you already know for ordinary fractions. Cancel common factors to simplify, find a common denominator to add, and flip to divide. The only new skill is factoring first so you can see what cancels.
In this lesson you will simplify algebraic fractions and combine them by adding, subtracting, multiplying and dividing. Factoring is the key that unlocks every step: once the numerator and denominator are in factored form, the common factors reveal themselves.
