Question

check whether 1, 2, 3, 0, -1, -2, -3 are zeroes of the polynomial
x ^{2} - 5x - 6.
i know in place of x we have to put the above no's. 

plzzzzzz say by solving it.​​

Answer 1

Answer:

only 3;-2 are the zeroes of the polynomial and are not the zeroes of the polynomial

Step-by-step explanation:

x^2-5x-6=x^2-3x+2x-6=x(x-3)+2(x-3)=(x-3)(x+2)

so the zeros of the polynomial are 3;-2
