Introduction to Linear Polynomials
1. Exercise Set 2.1
Q1. Find the degrees of the following polynomials.
(i) 2x² – 5x + 3
Solution: Degree = 2
(ii) y³ + 2y – 1
Solution: Degree = 3
(iii) – 9
Solution: Degree = 0
(iv) 4z – 3
Solution: Degree = 1
Q2. Write polynomials of degrees 1, 2 and 3.
Polynomial of Degree 1 :
Solution: 2x + 5
Polynomial of Degree 2 :
Solution: x² + 3x + 1
Polynomial of Degree 2 :
Solution: x³ – 2x² + x + 4
Q3. What are the coefficients of x² and x³ in the polynomial x⁴ – 3x³ + 6x² – 2x + 7?
Solution:
Coefficient of x² = 6
Coefficient of x³ = –3
Q4. What is the coefficient of z in the polynomial 4z³ + 5z² – 11?
Solution:
There is no z term in the polynomial.
Therefore, coefficient of z = 0
Q5. What is the constant term of the polynomial 9x³ + 5x² – 8x – 10?
Solution:
The constant term is the term without variable.
Therefore, constant term = –10
Polynomials of degree 1 are called linear polynomials.
