## How do you factor an equation into brackets?

In order to factorise a quadratic algebraic expression in the form ax2 + bx + c into double brackets:

- Multiply the end numbers together ( a and c ) then write out the factor pairs of this new number in order.
- We need a pair of factors that + to give the middle number ( b ) and ✕ to give this new number.

## How do you factorise 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 Factorised form?**

factored form (of a quadratic expression) A quadratic expression that is written as the product of a constant times two linear factors is said to be in factored form. For example, and are both in factored form.

**What is factorisation 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.

### What is the factoring formula?

Factoring quadratics is a method of expressing the quadratic equation ax2 + bx + c = 0 as a product of its linear factors as (x – k)(x – h), where h, k are the roots of the quadratic equation ax2 + bx + c = 0. This method is also is called the method of factorization of quadratic equations.

### How do you solve brackets in Bodmas?

The BODMAS rule states we should calculate the Brackets first (2 + 4 = 6), then the Orders (52 = 25), then any Division or Multiplication (3 x 6 (the answer to the brackets) = 18), and finally any Addition or Subtraction (18 + 25 = 43). Children can get the wrong answer of 35 by working from left to right.

**How do you expand a number with brackets?**

To expand a bracket means to multiply each term in the bracket by the expression outside the bracket. For example, in the expression 3 ( m + 7 ) , multiply both and 7 by 3, so: 3 ( m + 7 ) = 3 × m + 3 × 7 = 3 m + 21 .
