Answer 2

$\huge \fbox{answer}$

Given quadratic polynomial

x²-x-6

Let p(x) =x²-x-6

To find zeroes of p(x), we must take p(x)=0

x²-x-6 = 0

Splitting the middle term, we get

=>x²-3x+2x-6=0

=> x(x-3)+2(x-3)=0

=> (x-3)(x+2)=0

=> (x-3) =0 Or x+2 = 0

=> x = 3 Or x = -2

Therefore,

-2, 3 are zeroes of given polynomial x²-x-6
