The answer would be 1.6. The way you do this problem is you square the hypotenuse(in this case 11.56), then subtract the squared version on the side you do have (in this case 9). Then when you subrtact the two, find the square root of the difference (which would be 1.6 in this case).

Step-by-step explanation:

Given the equation :

2x²+ (4- k)x - 17 = 0

a = 2, c = - 17 b = (4 - k)

For the equation above to have one root; equal but opposite in sign

Then;

(ax + c) = 0 and b = 0

Since b = 0, the we can solve for k

b = 4 - k

b = 0

4 - k = 0

4 = k
