Medium Mathematics Quadratic Equations Class 10 Level 28

यदि किसी द्विघात समीकरण में (a=2), (b=-7), (c=3) हैं, तो समीकरण कौन-सा है?

If a quadratic equation has (a=2), (b=-7), (c=3), which equation is it?

Explanation opens after your attempt
Correct Answer

B. \(2x^2-7x+3=0\)

Step 1

Concept

Substituting in \(ax^2+bx+c=0\) gives \(2x^2-7x+3=0\). Keep the negative sign of (b).

Step 2

Why this answer is correct

The correct answer is B. \(2x^2-7x+3=0\). Substituting in \(ax^2+bx+c=0\) gives \(2x^2-7x+3=0\). Keep the negative sign of (b).

Step 3

Exam Tip

मानक रूप \(ax^2+bx+c=0\) में मान रखने पर \(2x^2-7x+3=0\) मिलता है। (b) का ऋण चिन्ह साथ रखें।
