\orange{\boxed{\boxed{\boxed{★ sOLUTIOn : }}}}

➡ x² - x - 6 = 0

➡ x² - 3x + 2x - 6 = 0

➡ x(x - 3) + 2(x - 3) = 0

➡ (x - 3)(x + 2) = 0

➡ x - 3 = 0 ; x + 2 = 0

➡ x = 0 + 3 ; x = 0 - 2

➡ x = 3 ; x = - 2

Hence, - 2 & 3 are the zeroes of the polynomial.

Answer:

suppose X=3

p(3)=3^2 - X - 6

= 9-3-6

=6-6

=0

therefore 3 is a zero

....,.....,......

suppose X= -2

p(-2)= -2^2-2-6

=4-2-6

=2-6

= -4

therefore -2 is not a zero
