Factor theorem class 9 questions
Factor theorem is commonly used for factoring a polynomial and finding the roots of the polynomial. It is a special case of a polynomial remainder theorem. As discussed in the introduction, a polynomial f(x) has a factor (x-a), if and only if, f(a) = 0. It is one of the methods to do the factorisation of a polynomial. See more Here we will prove the factor theorem, according to which we can factorise the polynomial. Consider a polynomial f(x) which is divided by (x-c), then f(c)=0. Using remainder theorem, f(x)= (x-c)q(x)+f(c) Where … See more The steps are given below to find the factors of a polynomial using factor theorem: Step 1 : If f(-c)=0, then (x+ c) is a factor of the polynomial f(x). Step 2 : If p(d/c)= 0, then (cx-d) is a factor of the polynomial f(x). Step … See more Factor theorem example and solution are given below.

Remainder Theorem states that if polynomial ƒ (x) is divided by a linear binomial of the for (x - a) then the remainder will be ƒ (a). Factor Theorem states that if ƒ (a) = 0 in this case, then the binomial (x - a) is a factor of polynomial ƒ (x). 3 comments ( 22 votes) Show more... Skyler Do

WebThe factor theorem enables us to factor any polynomial by testing for different possible factors. It basically tells us that, if ( x-c) is a factor of a polynomial, then we must have f ( c )=0. We can prove the factor theorem by considering that the outcome of dividing a polynomial f ( x) by ( x-c) is f (c)=0. Therefore, we can write: WebFactor theorem is mainly used to factor the polynomials and to find the n roots of that polynomial. It is a special kind of the polynomial remainder theorem that links the factors …
