Search: quadratic zeroes intercepts

Question Medium Mathematics Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 23

यदि (p(x)=2x^-2-8) है तो ग्राफ के शून्यक कौन से हैं?

Explanation opens after your attempt

Correct Answer

A. (2) और (-2)(2) and (-2)

Step 1

From \(2x^2-8=0\), \(x^2=4\) and \(x=\pm2\). Tip: simplify by the common factor first.

Step 2

The correct answer is A. (2) और (-2) / (2) and (-2). From \(2x^2-8=0\), \(x^2=4\) and \(x=\pm2\). Tip: simplify by the common factor first.

Step 3

\(2x^2-8=0\) से \(x^2=4\) और \(x=\pm2\) मिलता है। टिप: पहले समान गुणक से सरल करें।
