\(x^4-13x^2+36=0\) में \(y=x^2\) रखने पर कौनसा समीकरण मिलेगा?
If \(y=x^2\) is put in \(x^4-13x^2+36=0\), which equation is obtained?
Explanation opens after your attempt
Correct Answer
A. \(y^2-13y+36=0\)
Step 1
Concept
Since (x-4=\(x^2\)2=y-2), the new equation is \(y^2-13y+36=0\). In exams, substitution simplifies a difficult form.
Step 2
Why this answer is correct
The correct answer is A. \(y^2-13y+36=0\). Since (x-4=\(x^2\)2=y-2), the new equation is \(y^2-13y+36=0\). In exams, substitution simplifies a difficult form.
Step 3
Exam Tip
क्योंकि (x-4=\(x^2\)2=y-2), इसलिए नया समीकरण \(y^2-13y+36=0\) है। परीक्षा में प्रतिस्थापन कठिन रूप को सरल बनाता है।
