If c and k are the roots of 6-x-x^2=0 find c + k. pls solve like a quadratic equation

c + k = - 1

Step-by-step explanation:

given a quadratic equation in standard form : ax² + bx + c = 0 : a ≠ 0

Then the sum of the roots = - and

The product of the roots =

- x² - x + 6 = 0 is in standard form

with a = - 1, b = - 1 and c = 6

The roots are c and k, hence

c + k = - = - 1

-2 is the right

210/22 = 9.55

since he can't take part of a person to the game the answer is 9 people

hope this !
