MCQ
The circle x2 + y2 - 3x - 4y + 2 = 0 cuts x-axis:
- A(2, 0), (-3, 0)
- B(3, 0), (4, 0)
- C(1, 0), (-1, 0)
- D(1, 0), (2, 0)
Solution:
x2 + y2 - 3x - 4y + 2 = 0
x-axis will be cut when y = 0
put y=0
x2 - 3x + 2 = 0
(x - 2) (x - 1) = 0
x = 1, 2
points (1, 0), (2, 0)

In tossing a coin, the chance of throwing head and tail alternatively in 3 successive trials is:
$-\frac{4\text{x}}{(\text{x}^2-1)^2}$
$-\frac{4\text{x}}{\text{x}^2-1}$
$\frac{1-\text{x}^2}{\text{4x}}$
