Question

which of the following is a quadratic polynomial having zeroes 1 and -2 1 point x2 -x +2 x2 -x -2 x2 +x -2 x2 +x +2

Answer 1

Answer:

Step-by-step explanation:

The zeroes of polynomial are1&-2

So sum of the zeroes=-2+1=-1

And product of two zeroes=-2×1=-2

So the polynomial is x²-(-1)x+(-2)

=x²+x-2
