If -1 is one of the roots of the equation 3x² - 2k - 2x - 1 = 0, find the value of k.

snow_tiger [21]

Answer:

k = 2

Step-by-step explanation:

Given that x = - 1 is a root of the equation, then it satisfies the equation.

Substitute x = - 1 into the equation and solve for k, that is

3(- 1)² - 2k - 2(- 1) - 1 = 0

3 - 2k + 2 - 1 = 0

- 2k + 4 = 0 ( subtract 4 from both sides )

- 2k = - 4 ( divide both sides by - 2 )

k = 2
