Find a quadratic polynomial whose zeroes are +root 15 and -root 15.. pls its urgent
Answers
Step-by-step explanation:
let the quadratic equation ax^2 + bx + c
given zeroes are ✓15 and - ✓15
let a = 1
sum of zeroes = - ( b) / a
- ✓15 + ✓15 = - b / 1
0 = - b
0 = b
product of zeroes = c /a
- ✓15 × ✓15 = c / 1
- 15 = c
putting the values of a, b and c in the quadratic equation we get,
x^2 + (0)x -15
therefore, x^2 - 15

Step-by-step explanation:
Labour, as we all know, means work. What do we give an accent to this word and say dignity of labour. We can recall different kinds of work – from the physical labours of a farm-hand to the white-collar job as an executive in a large organisation. The highly placed executive, after years of successful career, begins to attach much dignity and self- respect to his job.
If he has travelled for years in a car, he thinks it is below his dignity to travel in a bus. One cannot expect such a person to do the job of an attendant even when it necessitates him to carry his own luggage. Though it may not affect any other individual, yet there is something in human about his sense of dignity and self-respect.
To know the true sense of the phrase, we should study the lives of some of our great leaders. We all know of an incident when an Englishman who was in search of a porter at a railway station to carry his luggage, when a humble man volunteered to carry his luggage. After depositing the luggage in the train, the man walked away. The man was Ishwar Chandra Vidyasagar, one of the freedom fighters in the days of the British rule.
Mahatma Gandhi, for instance, cut his own hair, washed his own clothes, cooked his own food and went on foot from place to place. He travelled with the mass in a third class railway coach.
Today, the Indian society is charged with the gusto of trade unionism.
