How do you Factorise for Class 9?

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

1. Find x = a where p(a) = 0.
2. Then (x – a) is the factor of p(x)
3. Now divide p(x) by (x – a) i.e. (p(x))/((x – a))
4. 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:

1. Find the highest common factor of each of the terms in the expression.
2. Write the highest common factor (HCF) in front of any brackets.
3. 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:

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