how to prime factorize the denominator of the given fraction
Answers
Answer:
factorisation or factoring is defined as the breaking or decomposition of an entity (for example a number, a matrix, or a polynomial) into a product of another entity, or factors, which when multiplied together give the original number or a matrix, etc. This concept you will learn majorly in your lower secondary classes from 6 to 8.
It is simply the resolution of an integer or polynomial into factors such that when multiplied together they will result in original or initial the integer or polynomial. In the factorisation method, we reduce any algebraic or quadratic equation into its simpler form, where the equations are represented as the product of factors instead of expanding the brackets. The factors of any equation can be an integer, a variable or an algebraic expression itself.
Factorisation
Maths Factorisation
To the factor, a number means to break it up into numbers that can be multiplied to get the original number. For example,
24 = 4 × 6 4 and 6 are the factors of 24
9 = 3 × 3 3 is the factor of 9
Also, numbers can be factorized into different combinations. There are different ways to find the Factors of a Number. To find the factors of an integer is an easy method but to find the factors of algebraic equations is not that easy. So let us learn to find the factors of quadratic polynomial.
Factorisation in Algebra
The numbers -12, -6, -2, -1, 1, 2, 6, and 12 are all factors of 12 because they divide 12 without a remainder. It is an important process in algebra which is used to simplify expressions, simplify fractions, and solve equations. It is also called as Algebra factorization.
Factorization Formula for a Quadratic Polynomial
A “quadratic” is a polynomial that is written like “ax2 + bx + c”, where “a”, “b”, and “c” are just numbers. For an easy case of factoring, you can identify the two numbers that will not only multiply to equal the constant term “c” but also add up to equal “b,” the coefficient on the x-term.
Factorising formulas algebra is especially important when solving quadratic polynomial When reducing formulas we normally have to remove all the brackets, but in particular cases, for example with fractional formulas, sometimes we can use factorisation to shorten a formula
Factorisation Example Problems
Here are some maths factorisation example questions and how to factorise the quadratic polynomial are explained in detail.
Factorise the Quadratic Polynomial:
x2 + 7x + 6
The constant term is 6, which can be written as the product of 2 and 3 or of 1 and 6. But 2 + 3 = 5, so 2 and 3 are not the numbers I need in this case. On the other hand, 1 + 6 = 7, so you can use 1 and 6:
x2 + 7x + 6 = (x+1)(x+6)
Note that the order doesn’t matter in multiplication, so the above answer can be written as “(x + 6)(x + 1).”
