(Q2)

Choose

The equation: \( (x - 3)(x + 4)(x - 1) = 0 \) is of what degree?

1. First
2. Second
3. Third
4. Fourth

(3).

Solution

1. Expand the equation to determine its degree.
2. \( (x - 3)(x + 4)(x - 1) = 0 \)
3. Multiplying the factors:
- First, \( (x - 3)(x + 4) = x^2 + x - 12 \)
- Then, \( (x^2 + x - 12)(x - 1) \)
4. The highest power of \( x \) in the resulting polynomial \( x^3 - x^2 - 13x + 12 \) is 3.

Therefore, the correct answer is: Third
