यदि (a=-2) हो, तो ((a+2)x-2+\(a^2-4\)x+7=0) किस प्रकार का कथन बनेगा?
If (a=-2), what type of statement will ((a+2)x-2+\(a^2-4\)x+7=0) become?

Correct Answer
A. विरोधाभासी कथनContradictory statement
Concept
Putting (a=-2) gives \(0x^2+0x+7=0\). This is (7=0), which is a contradictory statement.
Why this answer is correct
The correct answer is A. विरोधाभासी कथन / Contradictory statement. Putting (a=-2) gives \(0x^2+0x+7=0\). This is (7=0), which is a contradictory statement.
Exam Tip
(a=-2) रखने पर \(0x^2+0x+7=0\) मिलता है। यह (7=0) है, जो विरोधाभासी कथन है।
