यदि (a=-4) हो, तो ((a+4)x-2+\(a^2-16\)x+13=0) किस प्रकार का कथन बनेगा?
If (a=-4), what type of statement will ((a+4)x-2+\(a^2-16\)x+13=0) become?
Explanation opens after your attempt
A. विरोधाभासी कथनContradictory statement
Concept
Putting (a=-4) gives \(0x^2+0x+13=0\). This is (13=0), which is a contradictory statement.
Why this answer is correct
The correct answer is A. विरोधाभासी कथन / Contradictory statement. Putting (a=-4) gives \(0x^2+0x+13=0\). This is (13=0), which is a contradictory statement.
Exam Tip
(a=-4) रखने पर \(0x^2+0x+13=0\) मिलता है। यह (13=0) है, जो विरोधाभासी कथन है।
