Question 12 If |■8(2&4@5&1)|=|■8(2𝑥&4@6&𝑥)|, 𝑡ℎ𝑒𝑛 𝑡ℎ𝑒 𝑝𝑜𝑠𝑠𝑖𝑏𝑙𝑒 value(s) of ‘x’ is/are (a) 3 (b) √3 (c) −√3 (d) √3, −√3Given |■8(2&4@5&1)|=|■8(2𝑥&4@6&𝑥)| 2 × 1 − 5 × 4 = 2x × x − 6 × 4 2 − 20 = 2x2 − 24 −18 = 2x2 − 24 −18 + 24 = 2x2 6 = 2x2 2x2 = 6 x2 = 6/2 x2 = 3 x = ± √𝟑 Thus, x = √3, −√3 So, the correct answer is (d)
