Easy Mathematics Quadratic Equations Class 10 Level 33

किस समीकरण के मूल (-4) और (2) हैं?

Which equation has roots (-4) and (2)?

Explanation opens after your attempt
Correct Answer

A. \(x^2+2x-8=0\)

Step 1

Concept

With roots (-4) and (2), we get ((x+4)(x-2)=0). Expanding it gives \(x^2+2x-8=0\).

Step 2

Why this answer is correct

The correct answer is A. \(x^2+2x-8=0\). With roots (-4) and (2), we get ((x+4)(x-2)=0). Expanding it gives \(x^2+2x-8=0\).

Step 3

Exam Tip

मूल (-4) और (2) होने पर ((x+4)(x-2)=0) होगा। इसे खोलने पर \(x^2+2x-8=0\) मिलता है।
