To help a poor student, ariv donated α pens and β books to him, where α and β represent the zeroes of polynomial x^2-5x + 4. inspired by the deed of ariv,arya also donated 2α+ 3β pens and 3α + 2β books to that student. find a polynomial whose zeroes are the number of pens and books donated by arya. explain why arya got inspired by the deed of ariv.
Answers
Step-by-step explanation:
Given:To help a poor student, ariv donated α pens and β books to him, where α and β represent the zeroes of polynomial x²-5x + 4. inspired by the deed of ariv,arya also donated 2α+ 3β pens and 3α + 2β books to that student.
To find: find a polynomial whose zeroes are the number of pens and books donated by arya. explain why arya got inspired by the deed of ariv.
Solution:
As and are zeros of
So,According to relation of zeros and coefficient of quadratic polynomial
ATQ,
Arya donated pens
and books.
let
Quadratic polynomial with zeros m and n is given by
Find Value of m+n:
put value from eq1
Find mn:
find value of
Square eq1 both sides
put value of in eq4
Therefore, quadratic polynomial is
Final answer:
The quadratic polynomial is
Arya got inspired by the deed of ariv because helping poor students is a good behavior.
Hope it helps you.
