Answers

Answered by aliabidi09

Step-by-step explanation:

Let

P(x) = x^2 - x - 6

Put x = - 2

P(-2) = (-2)^2 - ( - 2) - 6

P(-2) = 4 +2 - 6

P(-2= 0

As its equal to 0 so

-2 is the zero of polynomial.

aiswaryanayak317: you did wrong

aiswaryanayak317: in the 4th step it was - 6 not +6

aliabidi09: oh sorry i mistakenly put +6

aliabidi09: thank you for pointing it out.
