यदि (p=3) और (q=-2), तो \(p^2q-2pq^2+q\) का मान क्या होगा?
If (p=3) and (q=-2), what is the value of \(p^2q-2pq^2+q\)?
Explanation opens after your attempt
A. (-44)
Concept
Substitution gives (9(-2)-2(3)(4)-2=-44). \(q^2\) will be positive but (q) remains negative.
Why this answer is correct
The correct answer is A. (-44). Substitution gives (9(-2)-2(3)(4)-2=-44). \(q^2\) will be positive but (q) remains negative.
Exam Tip
मान रखने पर (9(-2)-2(3)(4)-2=-44) मिलता है। \(q^2\) धनात्मक होगा लेकिन (q) ऋणात्मक रहेगा।
