Question

+
The zeroes of the polynomial x2 – 2x – 99 are
(a) -9 and 11
(b) 9 and 11
(c)-9 and -11
(d) 9 and​

Answer 1

Answer:

p(x) = x2 – 2x – 99 = 0

= x^2 -11x +9x -99 =0

= x (x-11) +9(x-11) = 0

= (x-11) (x+9) =0

(x-11) =0. and (x+9) =0

x = 11 and x = -9

Hence,The zeroes of the polynomial x2 – 2x – 99 are 11 & -9
