Answer 2

$\huge{ \underline{ \boxed{ \sf{ \purple{AnsweR :}}}}}$

• We are asked to find the zeroes of the polynomial.

• The polynomial is x² - 2x - 8

We can find the zeroes by splitting the middle term.

⟹ x² - 2x - 8

⟹ x² - 4x + 2x +- 8

⟹ x ( x - 4 ) + 2 ( x - 4 )

⟹ ( x - 4 ) ( x + 2 )

Let us make these equations equal to zero in order to find the value of x.

x - 4 = 0

$\boxed{x = 4}$

x + 2 = 0

$\boxed{x=-2}$

Hence, 4 & -2 are the zeroes of the given polynomial.
