Explain the following: Women workers in Britain attacked the Spinning Jenny In the seventeenth century merchants from towns in Europe began employing peasants and artisans within the villages The port of Surat declined by the end of the eighteenth century The East India Company appointed ‘gomasthas’ to supervise weavers in India Solution: James Hargreaves designed the Spinning Jenny in 1764. This machine speeded up the spinning process and reduced the demand for labour. By the use of this machine, a single worker could turn a number of spindles, and spin several threads at a time. Due to this, many weavers would lose employment. The fearful prospect of unemployment drew women workers, who depended on hand-spinning, to attack the new machine

  Access Answers to NCERT Class 10 Maths Chapter 4 – Quadratic Equations Exercise 4.1 Page: 73 1. Check whether the following are quadratic equations: (i) (x + 1) 2  = 2(x – 3) (ii) x 2  – 2x = (–2) (3 – x) (iii) (x – 2)(x + 1) = (x – 1)(x + 3) (iv) (x – 3)(2x +1) = x(x + 5) (v) (2x – 1)(x – 3) = (x + 5)(x – 1) (vi) x 2  + 3x + 1 = (x – 2) 2 (vii) (x + 2) 3  = 2x (x 2  – 1) (viii) x 3  – 4x 2  – x + 1 = (x – 2) 3 Solutions: (i) Given, (x + 1) 2  = 2(x – 3) By using the formula for (a+b) 2  = a 2 +2ab+b 2 ⇒ x 2  + 2x + 1 = 2x – 6 ⇒ x 2  + 7 = 0 Since the above equation is in the form of ax 2  + bx + c = 0. Therefore, the given equation is quadratic equation. (ii) Given, x 2  – 2x = (–2) (3 – x) ⇒ x 2  –   2x = -6 + 2x ⇒ x 2  – 4x + 6 = 0 Since the above equation is in the form of ax 2  + bx + c = 0. Therefore, the given equation is quadratic equation. (iii) Given, (x – 2)(x + 1) = (x – 1)(x + 3) By multiplication ⇒ x 2  – x – 2 = x 2  + 2x – 3 ⇒ 3x – 1 = 0 Since the above equation is no
