For this case what we should do is write correctly the given equation:
 D ^ 2 = W ^ 2 + H ^ 2
 We substitute the values:
 D = 17inch
 H = 9inch
 Substituting:
 17 ^ 2 = W ^ 2 + 9 ^ 2
 We clear the value of W:
 W = root (17 ^ 2 - 9 ^ 2)
 W = 14.4 inch
 Answer:
 The width of the laptop screen is:
 D. W = 14.4 inch
