समीकरण ((x-3)2+(x+4)2=(x-1)2) का मानक रूप कौन-सा है?
What is the standard form of ((x-3)2+(x+4)2=(x-1)2)?
Explanation opens after your attempt
Correct Answer
A. \(x^2+4x+24=0\)
Concept
Expanding gives left side \(2x^2+2x+25\) and right side \(x^2-2x+1\). Subtracting gives \(x^2+4x+24=0\).
Why this answer is correct
The correct answer is A. \(x^2+4x+24=0\). Expanding gives left side \(2x^2+2x+25\) and right side \(x^2-2x+1\). Subtracting gives \(x^2+4x+24=0\).
Exam Tip
विस्तार करने पर बाईं ओर \(2x^2+2x+25\) और दाईं ओर \(x^2-2x+1\) है। घटाने पर \(x^2+4x+24=0\) मिलता है।
