Correct Answer: B. \(x^{2} - 6x + 6 = 0\)

Explanation

\((x - \alpha)(x - \beta) = 0\)

\((x - (3 - \sqrt{3}))(x - (3 + \sqrt{3})) = 0\)

\((x^{2} - (3 - \sqrt{3})x - (3 + \sqrt{3})x + (9 + 3\sqrt{3} - 3\sqrt{3} - 3) = 0\)

\(x^{2} - 3x - x\sqrt{3} - 3x + x\sqrt{3} + 6 = 0\)

\(x^{2} - 6x + 6 = 0\)

Correct Answer: D) Tick

Explanation

This Biology question is asking us to identify the odd one out from a list of five insects. The options are Mosquito, Bee, Moth, Tick, and Beetle. The correct answer is Tick, which is option D. All the other options - Mosquito, Bee, Moth, and Beetle - are insects that belong to the class Insecta. Insects are characterized by having three body segments (head, thorax, and abdomen), three pairs of legs, and usually two pairs of wings. However, ticks are not classified as insects because they have four pairs of legs and two body segments. Ticks belong to the class Arachnida, which also includes spiders, scorpions, and mites. It is important to note that ticks are not insects, but they are still important because they can transmit diseases to humans and animals. Ticks are known to carry Lyme disease, Rocky Mountain spotted fever, and other illnesses. In conclusion, Tick is the odd one out from the list of insects because it is not an insect, but rather belongs to the class Arachnida.
