Answer 2

To find the zeros of the function Y = -9 - 10x - x^2, we need to solve the equation for when Y = 0:

0 = -9 - 10x - x^2

We can rearrange this equation to get:

x^2 + 10x + 9 = 0

This is a quadratic equation that we can solve using the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 1, b = 10, and c = 9.

Plugging in these values, we get:

x = (-10 ± sqrt(10^2 - 4(1)(9))) / 2(1) x = (-10 ± sqrt(64)) / 2 x = (-10 ± 8) / 2

So the solutions are:

x = (-10 + 8) / 2 = -1 x = (-10 - 8) / 2 = -9

Therefore, the zeros of the function Y = -9 - 10x - x^2 are x = -1 and x = -9.
