This is the basic and conceptual question from polynomials in which we have given a polynomial ax²-3(a-1)x-1 and it is also given that 1 is the zero of the given polynomial and we have to find the value of a.
Kindly give me a detailed solution of this question
RS Aggarwal, Class 10, chapter 2C, question no 8
Given : 1 is one of zeroes of the polynomial ax²−3(a−1)x−1 , which means x=1 will satisfy it.
a(1)²−3(a−1)1−1=0
a−3a+3−1=0
−2a+2=0
a=1
The value of a is 1.
