Question

define factorisation ​

Answer 1

$\huge{\bf{\underline{\red{Solution :}}}}$

Factorisation :

⇒When an algebraic expression is written as the product of two or more expressions so each of these expression is called Factorisation .

⇒The  process of writing an expression in terms of its factor is called Factorisation

$\bold{\green{Factorisation \ of \ Polynomials }}$

⇒We can factorise a polynomial by using these methods :

• By taking out common factors
• By grouping the terms having common factor
• By using the formula ( x² - y² ) = (x - y) (x + y)

⊕Factorisation by taking out common Factors :

• Find the HCF of the terms.
• Divide each of the terms by their HCF
• Express each term as the product of the HCF and the quotient in the above step.
• Take out the HCF .
