Some Questions from NCERT Solutions for Class 10 Maths Chapter 2 – Polynomials
Q.1 Write the coefficients of x2 in each of the following: (0)2 + x2+x (192-x2 + x2 (nuo 5×2+x (v) vāx-1
Coefficient of x2 in ax2 + bx+c = 0 is a.
Hence, coefficients of x
(0) 2 + x2 + x is 1
(ii) 2 – x2 + x3 is -1
que <x+x is
(iv) vēx-1 is o
Q.2. Give one example each of a binomial of degree 35 and of a monomial of degree 100.
Binomial of degree 35 may be taken as 435 + 4x And monomial of degree 100 may be taken as 5×100
Note: This question might have different answers.
Q.3. Write the degree of each of the following polynomials: (0) 5×3 + 4×2 + 7x (ii) 4 – 2 (ii) 5t-vi (iv) 3
(1) The power of the term is 5y3 and exponent is 3. So the degree is 3.
(ii) The power of the term is 72 and exponent is 2. So the degree is 2.
(iii) The power of the term is 5t and exponent is 1. So the degree is 1.
(iv) The only term here is 3 which can be written as 3yo and so the exponent is o or degree is 0.
Q.4. Classify the following as linear, quadratic and cubic polynomials: (1) x2 + x (ii) x-x? (lii) y+ y2 + 4 (iv) 1 + x
( 137 (vi) 2 (vii) 7x2
(0) The highest degree of y2 + x is 2, so it is a quadratic polynomial.
(ii) The highest degree of x- y3 is 3, so it is a cubic polynomial.
(iii) The highest degree of y + y2 + 4 is 2, so it is a quadratic polynomial.
(iv) The highest degree of x in (1 + x) is 1, so it is a linear polynomial.
(v)The highest degree of tin 3t is 1, so it is a linear polynomial.
(vi)The highest degree of 2 is 2, so it is a quadratic polynomial.
(vii) The highest degree of x in 7×3 is 3, so it is a cubic polynomial.
