Answer:
Step-by-step explanation:
1). Geometric mean of a and b =
Therefore, geometric mean of 2 and 50 =
= 10
2). By geometric mean theorem,
e² = 6 × 24
e = √144
e = 12
Similarly,
d² = 6 × 30
d = √180
d = 6√5
And
c² = 30 × 24
c = √720
c = 12√5
Correct Answer:
3rd option is the correct answer
Solution:
The zeros of the polynomial are -1,1 and 3. The multiplicity of 3 is 2. So the polynomial can be expressed as:
The y-intercept of the polynomial is -18. This means the polynomial passes through the point (0,-18). Therefore, y must be -18 when x = 0. Using these values of x and y in previous equation we get:
The final equation of the polynomial becomes:
