Correct Answer

A. (-44)

Step 1

Concept

Substitution gives (9(-2)-2(3)(4)-2=-44). \(q^2\) will be positive but (q) remains negative.

Step 2

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.

Step 3

Exam Tip

मान रखने पर (9(-2)-2(3)(4)-2=-44) मिलता है। \(q^2\) धनात्मक होगा लेकिन (q) ऋणात्मक रहेगा।
