Question

verify whether 2 and 1 are zeroes of polynomial x^2-6x+8​

Answer 1

Answer:

Equating the expression with 0,

x

2

−6x+8=0

On factorising it further,

x

2

−4x−2x+8=0

x(x−4)−2(x−4)=0

(x−4)(x−2)=0

∴x=4 or x=2

Answer 2

2 is the only zero of the polynomial

Step-by-step explanation:

With 2 : 4 - 12 + 8

12 - 12

0

With 1 : 1 - 6 + 8

9 - 6
