This question is taken from polynomials in which we have given a polynomial kx²+3x+k and we have been asked to find the value of k if one zero of the given polynomial is 2.
Kindly solve the above problem.
RS Aggarwal, Class 10, chapter 2C, question no 5
Given : 2 is one of zeroes of the polynomial kx²+3x+k, which means x=2 will satisfy it.
k(2)²+3(2)+k=0
4k+6+k=0
5k+6=0
k=−6/5
The value of k is −6/5
