Medium Mathematics Quadratic Equations Class 10 Level 29

किस समीकरण में (b=0) और (c>0) है?

Which equation has (b=0) and (c>0)?

Explanation opens after your attempt
Correct Answer

B. \(5x^2+20=0\)

Step 1

Concept

In \(5x^2+20=0\), the (x) term is absent, so (b=0) and (c=20>0). Treat a missing term coefficient as (0).

Step 2

Why this answer is correct

The correct answer is B. \(5x^2+20=0\). In \(5x^2+20=0\), the (x) term is absent, so (b=0) and (c=20>0). Treat a missing term coefficient as (0).

Step 3

Exam Tip

\(5x^2+20=0\) में (x) पद अनुपस्थित है, इसलिए (b=0) और (c=20>0) है। अनुपस्थित पद का गुणांक (0) मानें।
