![]() ![]() In case you have been asked to solve inequalities involving monomials, factoring can be very helpful in these problems as it helps find roots from both positive and negative ends which you will need to use in the process of solving the inequality. ![]() Factoring Helps Solve Inequalities Involving Monomials However, if it has to be solved in the form of (3x+6) (x-4)=0, then you will need some other technique. However, many people find this complicated for multiplying binomials when they are not written in standard form.įor instance, if you want to solve the equation 3 x2+ 7x-18=0, then there will be no issue when you have to use the quadratic formula. There are several techniques proving that quadratic equations can be solved using the quadratic formula in case it is written in standard form (ax² + bx + c= 0). Factoring Helps To Solve Quadratic Equations Using The Quadratic Formula In such cases, you can use factoring to simplify these operations. However, this method becomes time consuming and tedious when multiplying polynomials with a large number of terms. This method is extremely useful for simplifying long multiplication problems involving binomials and trinomials. One of the most important uses of factoring is multiplying polynomials using FOIL (First, Outer, Inner, Last) method. Factoring Helps Multiply Polynomials Using FOIL Method As you indulge in the complex task of solving equations, your brain is trained to become sharper and more analytical. Using your brain to solve intricate stuff using factoring is a way to train your brain for sharpness. It also helps when finding formula for quadratic equations like (x-h)2 = 4p or (x+h)2=4p to solve problems in geometry and algebra. Factoring Helps Create Perfect Squaresįactoring helps create perfect squares when you are given equation in the form x2 = b, where ‘b’ is an integer. ![]() You can use it to find factors of a number or factorization of one number into its prime factors and do so much more of the basic math that you otherwise can never ace at. Factoring Is A Needed Skill In Schoolsįactoring is one of the most important skills required to pass math tests, just like logic and science, especially at high school level. It can also help you check if two numbers are coprime (i.e., they have no factors in common). It can be particularly helpful in simplifying fractions and finding equivalent fractions. Factoring Helps Find The Least Common Denominator (LCD)Īnother useful application of factoring is finding the least common denominator (LCD) of different fractions. Factoring helps find LCM of a set of numbers or factorization of one number into its prime factors. LCM can be particularly helpful in simplifying fractions and checking if two numbers are coprime (i.e., they have no factors in common). Thus, it is important to understand the importance of factoring before using this algorithm for numerical operations.Īnother important use of factoring is in finding the least common multiple (LCM). This is especially true when you have to perform multiple divisions by different divisors. Polynomial long division method is not as fast as the factoring method. You can use the factoring method to speed up polynomial long division. Factoring Helps To Speed Up Polynomial Long Division This article discusses 15 reasons explaining why factoring is important in math: 1.
