The zeroes of the polynomial p (x) = 2x2 + 5x - 3 are
A.

B.

C.

D.

Answer :

We have,

p (x) = 2x2 + 5x - 3


So, zero of the given polynomial can be calculated as follows:


2x2 + 5x – 3 = 0


2x2 + 6x – x – 3 = 0


2x (x + 3) – 1 (x + 3) = 0


(2x – 1) (x + 3) = 0


Now, (2x – 1) = 0


2x = 1



Also, (x + 3) = 0


x = -3


Hence, zeros of the given polynomial are and – 3
