Here,

We factorise 2x + 4 to get 2 (x + 2)

 

In this chapter, we will learn how to factorise by different methods

  • Factorisation by common factor
  • Factorisation by regrouping
  • Factorisation by using identities
  • Factorisation by splitting the middle term

Factorization of Algebraic Expression

Algebraic expressions have numbers & variable in it

Example :

  • 5xy
  • 28 x 2 yz
  • 41x
  • 98y 2 z 4

Let’s learn how to factorise it

 

Factorisation of 5xy

  5xy = 5 × x × y

 

Factorisation of 28x 2 yz

  28x 2 yz = 2 × 2 × 7 × x 2 × y × z

= 2 × 2 × 7 × x × x × y × z

 

Factorisation of 41x

  41x = 41 × x

 

Factorisation of 98y 2 z 4

  98y 2 z 4 = 2 × 7 × 7 × y 2 × z 4

= 2 × 7 × 7 × y × y × z × z × z × z
