## How do you Factorise for Class 9?

Now, suppose p(x) is divided by (x − a), then quotient is g(x). By remainder theorem, when p(x) is divided by (x − a), then remainder is p(a). On dividing p(x) by (x − a), let g(x) be the quotient.

## What is factorisation method example?

Factorisation is the process of reducing the bracket of a quadractic equation, instead of expanding the bracket and converting the equation to a product of factors which cannot be reduced further. For example, factorising (x²+5x+6) to (x+2) (x+3). Here, (x+2) (x+3) is factorisation of a polynomial (x²+5x+6).

**How do you factor a cubic polynomial class 9?**

Factorising Cubic Polynomial

- Find x = a where p(a) = 0.
- Then (x – a) is the factor of p(x)
- Now divide p(x) by (x – a) i.e. (p(x))/((x – a))
- And then we factorise the quotient by splitting the middle term.

**What is the formula of factorization?**

The general factorization formula is expressed as N = Xa × Yb × Zc. Here, X, Y, Z represent the factors of a factorized number.

### What is factorisation formula?

The general factorization formula is expressed as N = Xa × Yb × Zc. Here, a, b, c represent the exponential powers of the factors of a factorized number.

### How do you factorise a question?

The simplest way of factorising is:

- Find the highest common factor of each of the terms in the expression.
- Write the highest common factor (HCF) in front of any brackets.
- Fill in each term in the brackets by multiplying out.

**How do you Factorise?**

**What is factorise method?**

Factorisation is a method of breaking the arithmetic algebraic expressions into the product of their factors. If we multiply the factors again, then they will result in original expression.

#### How do you factorise steps?

How to factorise quadratics:

- Write out the factor pairs of the last number (c).
- Find a pair of factors that + to give the middle number (b) and multiply to give the last number (c).
- Write two brackets and put the variable at the start of each one.
