किसी परवलय का एक शून्यक (-10) है और दूसरा शून्यक पहले से (18) अधिक है। सममिति अक्ष क्या होगा?

One zero of a parabola is (-10), and the other zero is (18) more than the first. What is the axis of symmetry?

Explanation opens after your attempt
Correct Answer

A. (x=-1)

Step 1

Concept

The other zero is (8), and the average is \(\frac{-10+8}{2}=-1\). Tip: the axis of symmetry is the average of two zeroes.

Step 2

Why this answer is correct

The correct answer is A. (x=-1). The other zero is (8), and the average is \(\frac{-10+8}{2}=-1\). Tip: the axis of symmetry is the average of two zeroes.

Step 3

Exam Tip

दूसरा शून्यक (8) है और औसत \(\frac{-10+8}{2}=-1\) है। टिप: सममिति अक्ष दो शून्यकों का औसत है।
