Question

verify whether -2and 3 are zeroes of the polynomial x²-x-6
or not ​

Answer 1

Answer:

True

Step-by-step explanation:

Substituting -2 in place of x, we get

$=(-2)^{2} -(-2)-6\\=4+2-6\\=6-6\\=0$

Hence -2 is a zero of polynomial

Substituting 3 in place of x, we get

$=3^{2} -3-6\\=9-3-6\\=9-9\\=0$

Hence 3 is a zero of polynomial
