\(10x^2-90=0\) को पहले सरल करने पर क्या मिलेगा?
What will be obtained first after simplifying \(10x^2-90=0\)?
Explanation opens after your attempt
A. \(x^2-9=0\)
Concept
Dividing both sides by (10) gives \(x^2-9=0\). In exams, simplifying the equation first saves time.
Why this answer is correct
The correct answer is A. \(x^2-9=0\). Dividing both sides by (10) gives \(x^2-9=0\). In exams, simplifying the equation first saves time.
Exam Tip
दोनों पक्षों को (10) से भाग देने पर \(x^2-9=0\) मिलता है। परीक्षा में पहले समीकरण को सरल करना समय बचाता है।
