According to the factor theorem, let p(x) be a polynomial of degree greater than or equal to one () and a be a real number so that p(a) = 0, then (x \u2013 a) is the factor of p(x). In reverse, if (x \u2013 a) is a factor of p(x), then p(a) = 0. Important Definitions, Examples, etc., are also mentioned in this article in simple language, which is easy to understand by the students.<\/p>\n<p>Moreover, we have attached the RD Sharma Chapter 6 Class 9 Maths Exercise 6.4 Solutions PDF for the learners from which they may practice for the exam.
