Q1. Find the sum by suitable rearrangement:
(a) 837 + 208 + 363
(b) 1962 + 453 + 1538 + 647

Answer:
(a) 837 + 208 + 363
= (837 + 363) + 208
= 1200 + 208
= 1408

(b) 1962 + 453 + 1538 + 647
= (1962 + 1538) + (453 + 647)
= 3500 + 1100
= 4600

Polynomials

(Important Points)

CBSE Class 9 - Maths Chapter 2

① A combination of constants and variables which are connected by basic mathematical operations, is known as Algebraic Expression. For e.g. x² – 7x + 2, xy² – 3 etc.

② A Polynomials p(x) in one variable x is an algebric expression in x of the form
p(x) = a_nxⁿ + a_n–1x^n–1 + ... + a₁ x + a₀ , where a₀ , a₁ , a₂ ..... a_n are constant and a n ≠ 0 are called coefficients and n is a positive integer.

③ The highest power of variable x in a polynomial p(x) is called the degree of the polynomial.

④ A polynomial of degree 1 is called a linear polynomial. For e.g. 4x + 9 is a linear polynomial in x.
