समीकरण ((x+2)2-(x+2)-6=0) को सरल करने पर कौन-सा द्विघात समीकरण मिलेगा?

Which quadratic equation is obtained by simplifying ((x+2)2-(x+2)-6=0)?

Explanation opens after your attempt
Correct Answer

A. \(x^2+3x-4=0\)

Step 1

Concept

((x+2)2=x-2+4x+4), so the simplified form is \(x^2+3x-4=0\). Write every term while opening brackets.

Step 2

Why this answer is correct

The correct answer is A. \(x^2+3x-4=0\). ((x+2)2=x-2+4x+4), so the simplified form is \(x^2+3x-4=0\). Write every term while opening brackets.

Step 3

Exam Tip

((x+2)2=x-2+4x+4) है, इसलिए सरल रूप \(x^2+3x-4=0\) है। कोष्ठक खोलते समय हर पद लिखें।
