Medium Mathematics Quadratic Equations Class 10 Level 32

किस समीकरण के मूल (-3) और (6) हैं?

Which equation has roots (-3) and (6)?

Explanation opens after your attempt
Correct Answer

A. \(x^2-3x-18=0\)

Step 1

Concept

With roots (-3) and (6), we get ((x+3)(x-6)=0). Expanding it gives \(x^2-3x-18=0\).

Step 2

Why this answer is correct

The correct answer is A. \(x^2-3x-18=0\). With roots (-3) and (6), we get ((x+3)(x-6)=0). Expanding it gives \(x^2-3x-18=0\).

Step 3

Exam Tip

मूल (-3) और (6) होने पर ((x+3)(x-6)=0) होगा। इसे खोलने पर \(x^2-3x-18=0\) मिलता है।
