Answer: k < 2 or k > 6.

Step-by-step explanation:

2x - k = xˆ2 + kx - 2

xˆ2 + (k - 2)x + (2 - k) = 0

For the line to meet the curve at two distinct points, this quadratic equation must have two distinct real roots. In other words, the discriminant (bˆ2 - 4ac) must be greater than zero:

(k - 2)ˆ2 - 4(2 - k) > 0

kˆ2 - 8k + 12 > 0

(k - 6)(k - 2) > 0

This inequality is satisfied when k < 2 or k > 6. Therefore, the set of values of k for which the line y= 2x-k meets the curve y= xˆ2+kx-2 at two distinct points is k < 2 or k > 6.
