Easy Mathematics Quadratic Equations Class 10 Level 30

यदि (a=3,\ b=0,\ c=-12) हैं तो संबंधित द्विघात समीकरण कौन-सा है?

If (a=3,\ b=0,\ c=-12), which is the corresponding quadratic equation?

Explanation opens after your attempt
Correct Answer

A. \(3x^2-12=0\)

Step 1

Concept

Substituting in \(ax^2+bx+c=0\) gives \(3x^2+0x-12=0\). Simplifying gives \(3x^2-12=0\).

Step 2

Why this answer is correct

The correct answer is A. \(3x^2-12=0\). Substituting in \(ax^2+bx+c=0\) gives \(3x^2+0x-12=0\). Simplifying gives \(3x^2-12=0\).

Step 3

Exam Tip

मानक रूप \(ax^2+bx+c=0\) में मान रखने पर \(3x^2+0x-12=0\) मिलता है। इसे सरल करने पर \(3x^2-12=0\) है।
