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
Find zeros of polynomial:
Thus,zeros of polynomial are
and
