Question

if one zero of the quadric polynomial x2+x-2 is -2 find the other zero
​

Answer 1

Answer:

m = 1

Step-by-step explanation:

Let the zeroes be m and n.

According to properties:

$m + n = \frac{ - b}{a}$

Here:

$b = 1 \: and \: a = 1$

Therefore:

$m + n = - 1$

Given that n = -2

$m = 1$
