If one of the number is excluded, the mean gets reduced by 2. Monomials are the building blocks of polynomials. Factorize each of the following: i ii iii iv v Ans. Recall, π is defined as the ratio of the circumference say c of a circle to its diameter say d.

Are you surprised by your answer? Therefore, degree of polynomial is 2. It is a polynomial that comprises variables and coefficients without subtraction or addition. The solutions given for the questions asked related to these topics will help the students to understand the concept better. Determine which of the following polynomials has a factor: i ii iii iv Ans. Answer No, the square roots of all positive integers are not irrational. Let us divide the polynomial by , to get Therefore, we can conclude that on factorizing the polynomial , we get.

Let us divide the polynomial by , to get Therefore, we can conclude that on factorizing the polynomial , we get. Answer We observe that when q is 2, 4, 5, 8, 10… then the decimal expansion is terminating. . What will be their mean monthly salary for December month? Class 9 Maths chapter 2 exercise 2.

Complex Numbers a Definition of a Complex Number b Set of Complex Numebrs c Conjugate of a Complex Number d Equality of Complex Numbers and its Properties Problem loading Video or seeking questions? Give possible expressions for the length and breadth of each of the following rectangles, in which their areas are given: i Area : 25a 2 — 35a + 12 ii Area : 35 y 2 + 13 y — 12 Answer i Area : 25a 2 — 35a + 12 Since, area is product of length and breadth therefore by factorizing the given area, we can know the length and breadth of rectangle. Therefore, the expansion of the expression is. In this chapter, Polynomials, the student will learn about the important concepts such as Zeroes of a Polynomial, Remainder Theorem. Therefore, we can conclude that the desired result is verified. These solutions come in extremely handy as students would no longer have to pile up their doubts and can instantly clear them from here. Let us substitute 1 in the polynomial , to get Thus, according to factor theorem, we can conclude that is a factor of the polynomial.

We will keep adding updated notes, past papers, guess papers and other materials with time. Therefore, we conclude that is a factor of. Evaluate the following products without multiplying directly: i ii iii Ans. If remainder comes out to be 0 then 7 + 3 x will be a factor of 3 x 3 + 7 x.
