Question

check whether x=-1 is a zero of polynomial P(x)=x²-4x+3. {or suno agar brainiest chaiye to fir full answer dena short nai}​

Answer 1

Answer:

for checking wheather x = -1 is a zero of polynomial= P(x) = x^2 - 4x +3

P(-1) = (-1)^2 - 4(-1) + 3

= 1 +4 +3

=8

hence it is not zero of polynomial
