# If c and k are the roots of 6 - x - x2 = 0, find c + k

### Question

If c and k are the roots of 6 - x - x2 = 0, find c + k

A) 2

B) 1

C) -1

D) -3

### Explanation:

6 - x - x2 = 0

a = -1; b = -1; c = 6

Sum of roots = c + k = -$$\frac{-b}{a}$$

= $$\frac{-(-1)}{-1}$$

= -1

## Dicussion (1)

• 6 - x - x2 = 0

a = -1; b = -1; c = 6

Sum of roots = c + k = -$$\frac{-b}{a}$$

= $$\frac{-(-1)}{-1}$$

= -1
