Q. 23.8( 4 Votes )

The zeroes of the polynomials x2 – x – 6 are:
A. 1, 6

B. 2, –3

C. 3, –2

D. 1, –6

Answer :

Solving the quadratic part,

x2 - x – 6 = 0


x2 - 3x + 2x – 6 = 0


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


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


Solving first part,


x + 2 = 0


x = - 2


Solving second part,


x - 3 = 0


x = 3


So the correct answer is C [3, -2].
