Question

This graph demonstrates the correlation between the number
of species and the area of landmass. Solid circles are more
distant islands, meaning they are significantly farther away from
the main land.

Answer 1

Here, p(x) = x2 + 2x – 195 Let p(x) = 0 ⇒ x2 + (15 – 13)x – 195 = 0 ⇒ x2 + 15x – 13x – 195 = 0 ⇒ x (x + 15) – 13(x + 15) = 0 ⇒ (x + 15) (x – 13) = 0 ⇒ x = –15, 13 Hence, the zeroes are –15 and 13.Read more on Sarthaks.com - https://www.sarthaks.com/1112202/find-the-zeroes-of-the-polynomial-x-2-2x-195
