Answer:

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 = - \frac{b}{a} and

The product of the roots = \frac{c}{a}

- 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 = - \frac{-1}{-1} = - 1

Problem
Paraphin [41]

Answer:

45/126 or 5/14

Step-by-step explanation:

a / b = 5/8

b / c = 9/14

a = 5

b = 8

b = 9

8 * 9 = 72

b = 72

If b was = 8 and now = 72, multiply a by 9.

b = 45

If b was 9 and now is 72, multiply c by 9.

c = 14 * 9 = 140 - 14 = 126


b / c = 45/126 or 5/14

You are welcome!
