Question

let R be the relation from the set a={1,2,3} on itself and defined by R={(1,1)(1,3)(3,3)(4,4)} then find the metarix of R.​

Answer 1

p(x) =4x² - 4x - 3

=> 4x² - 6x + 2x - 3

=> 2x( 2x -3) + 1(2x + 3)

=> (2x + 1) (2x -3)

p(x) = 0

(2x + 1) = 0 or (2x-3) = 0

x=-1/2 or x= 3/2

Hence, -1/2 and 3/2 are the zeroes of p(x).
