It is possible to factorise 4x²-9 further.
Factorising is to express a number or expression as a product of factors.
The technique of factorising two terms: a² - b² = (a + b) (a - b)
If we apply ( 4x²-9 ) to the previous technique: 4x² - 9 = (2x + 3) (2x - 3)

To factorise is to find the numbers that divide into the original number by only using prime numbers. For example factorise 20 = 2 times 2 times 5
The answer will depend on where the brackets are. In general the solution would be to expand all the brackets, combine like terms and then factorise.

Well, factorising fully is like finding the hidden treasures within a math problem. It means breaking down an expression into its simplest forms, like finding the roots of a beautiful flower. By factoring fully, you reveal all the factors that make up the original expression, allowing you to see its true beauty and simplicity. Just like adding colors to a painting, factorising fully helps us understand the expression better and appreciate its uniqueness.

To factorise is to find the numbers that divide into the original number by only using prime numbers. For example factorise 20 = 2 times 2 times 5
