Mathematics NCERT Grade 10, Chapter 2, Polynomials chapter starts by citing about degrees of polynomial and differentiation of polynomials based on its degree. Let us take an example, p(x) = x2+1 is a polynomial to be divided by g(x)=x. Find a cubic polynomial with the sum, sum of the product of its zeroes taken two at a time, and the product of its zeroes as 2, â7, â14 respectively. Understand the steps to divide a polynomial by a polynomial. From the formulas of sum and product of zeroes, we know, â´ If Î± and Î² are zeroes of any quadratic polynomial, then the quadratic polynomial equation can be written directly as:-. You can easily learn the new concepts and solve the exercise questions by using the NCERT Solutions Class 10 Maths Chapter 2 and complete this chapter. Divide the polynomial p(x) by the polynomial g(x) and find the quotient and remainder in each of the following: Dividend = p(x) =x4 â 5x + 6 = x4 +0x2â5x+6. Thus, 3x2-3â2x+1 is the quadratic polynomial. We study the division algorithm for polynomials of integers and also whether the zeroes of quadratic polynomials are related to their coefficients. (iv) In the given graph, the number of zeroes of p(x) is 2 because the graph intersects the x-axis at two points. Therefore, we say that, t2-3 is a factor of 2t2+3t+4. So, its zeroes are given by:Â x= â1Â andÂ x = â1. Obtain all other zeroes of 3x4+6x3-2x2-10x-5, if two of its zeroes are â(5/3) and â â(5/3). Find g(x). The syllabus is designed in such a way that the students can gather knowledge and develop a conceptual foundation to carry on to the advanced classes. Thus, x2â4x+1 is the quadratic polynomial.

(ii) __, 13, __, 3. Thus,4x2+x+1 is the quadratic polynomial. If the zeroes of the polynomial x3-3x2+x+1 are a â b, a, a + b, find a and b. Sum of zeroes = 0+(-2) = -2 = -(8/4) = = -(Coefficient of u)/(Coefficient of u2), Product of zeroes = 0Ã-2 = 0 = 0/4 = (Constant term)/(Coefficient of u2 ), Therefore, zeroes of polynomial equation t2 â15 are (â15, -â15), Sum of zeroes =â15+(-â15) = 0= -(0/1)= -(Coefficient of t) / (Coefficient of t2), Product of zeroes = â15Ã(-â15) = -15 = -15/1 = (Constant term) / (Coefficient of t2 ), â 3x2â4x+3xâ4 = x(3x-4)+1(3x-4) = (3x â 4)(x + 1), Therefore, zeroes of polynomial equation3x2 â x â 4 are (4/3, -1), Sum of zeroes = (4/3)+(-1) = (1/3)= -(-1/3) = -(Coefficient of x) / (Coefficient of x2), Product of zeroes=(4/3)Ã(-1) = (-4/3) = (Constant term) /(Coefficient of x2 ). Also verify the relationship between the zeroes and the coefficients in each case: â´ p(1/2) = 2(1/2)3+(1/2)2-5(1/2)+2 = (1/4)+(1/4)-(5/2)+2 = 0.
