1. निम्नलिखित द्विघात समीकरणों में से प्रत्येक समीकरण का विविक्तकर ज्ञात कीजिए।

(i) 2x - 7x + 6 = 0 (ii) 3x² - 2x - 8 = 0 (iii) 2

$2x ^{2} - 7x + 6 = 0$

(iv) /3x2 +2/2x-2/3 = 0 (v) (x - 1)(2x- 1) = 0 (vi) 1-x= 2x2

(vii) x2-2x + 1 = 0 (viii) 312-2x +2= 0

Answer 2

Answer:

The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
