What is factorisation?
In mathematics, factorization or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind.
Now, 4x²+27 can be written as 2².x²+9.3
=2².x²+3².(√3)²
=(2x+3√3)²
Hence, the equivalent expression is (2x+3√3)².
