Direction: Read the following text and answer the following questions on the basis of the same:
For a linear polynomial kx + c, k ≠ 0, the graph of y = kx + c is a straight line which intersects the X-axis at exactly one point, namely, Therefore, the linear polynomial kx + c, k ≠ 0, has exactly one zero, namely, the X-coordinate of the point where the graph of y = kx + c intersects the X-axis.
If the product of the zeroes of the quadratic polynomial p(x) = ax2 – 6x – 6 is 4, then the value of a is:
  • a)
  • b)
    3/2
  • c)
    2/3
  • d)
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
Direction: Read the following text and answer the following questions...
We have,
p(x) = ax2 – 6x – 6
Let α and β be the zeroes of the given polynomial, then
αβ = c/a
i.e., 4 = -6/a
⇒ 4a = – 6
