Algebraic Fractions
Gbogbo ọrọ náà
Algebraic fractions are fractions whose numerators and denominators contain letters. They behave exactly like ordinary fractions, but factorising first often reveals a common factor that cancels, turning a fearsome-looking expression into something simple.
In this lesson (Extended tier) you will simplify algebraic fractions by factorising and cancelling, and add, subtract, multiply and divide rational expressions.
Ebumnobi
- Manipulate algebraic fractions.
- Factorise and simplify rational expressions.
