## Practice questions for Factorization

In mathematics , factorization or factorisation , see English spelling differences 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. However, a meaningful factorization for a rational number or a rational function can be obtained by writing it in lowest terms and separately factoring its numerator and denominator. Factorization was first considered by ancient Greek mathematicians in the case of integers. They proved the fundamental theorem of arithmetic , which asserts that every positive integer may be factored into a product of prime numbers , which cannot be further factored into integers greater than 1.

Take a physical copy for the uninterrupted study hours of the student as these hard copies can be taken anywhere to practice any time, along with friends also.

Here the introduction may remind the knowledge of factors for the students which they have studied in the earlier classes.

Factoring called "Factorising" in the UK is the process of finding the factors: Factoring: Finding what to multiply together to get an expression. See how well you understand this notion by taking the quiz below! The median of these numbers Tell me about your worst boss.

#### Worked example 10: Factorising using a switch around in brackets

Factorization consists of writing a number or mathematical expression as a product of several factors, usually smaller or simpler expressions of the same kind. Factorization can be done on natural numbers and algebraic expressions. Factorizing a natural number is easy as compared to algebraic expressions. Most natural numbers factorization involves prime factors. Algebraic expression involves linear equations, quadratic equations, cubic equations and higher-order polynomials.

Sometimes, in order to factorise an expression as fully as possible, you need a combination of quadratic factorisation with the taking out of other common factors. Try to simplify the expression in the brackets. If it is a quadratic expression, try to factorise it. Substitute the values into the quadratic formula and simplify. To make the factorisation correct we have to multiply by the coefficient of x 2 in the original quadratic, that is multiply by A.
