\(x^2+8x-33=0\) के मूल क्या हैं?
What are the roots of \(x^2+8x-33=0\)?
Explanation opens after your attempt
A. (x=3,-11)
Concept
Since ((x+4)2=49), \(x+4=\pm7\), so (x=3,-11). In exams, use \(\pm\) to get both answers.
Why this answer is correct
The correct answer is A. (x=3,-11). Since ((x+4)2=49), \(x+4=\pm7\), so (x=3,-11). In exams, use \(\pm\) to get both answers.
Exam Tip
((x+4)2=49), इसलिए \(x+4=\pm7\) और (x=3,-11) हैं। परीक्षा में \(\pm\) से दोनों उत्तर निकालें।
