If $k$ is the smallest positive integer such that two quadratic functions $f(x) = (k - 1)x^2 + kx - 1$ and $g(x) = (k - 2)x^2 + x + 2k$ intersect at two different points $(x_1, y_1)$ and $(x_2, y_2)$ , then the quadratic equation with roots $x_1 + x_2$ and $y_1 + y_2$ is....

$x^2 - 1 = 0$

$x^2 + 4x - 5 = 0$

$x^2 - 10x = 0$

$x^2 - 6x - 7 = 0$
