यदि (a=2), (b=0), (c=-18) हैं तो समीकरण क्या होगा?
If (a=2), (b=0), (c=-18), what is the equation?
Explanation opens after your attempt
A. \(2x^2-18=0\)
Concept
Substituting in standard form gives \(2x^2+0x-18=0\). This is written as \(2x^2-18=0\).
Why this answer is correct
The correct answer is A. \(2x^2-18=0\). Substituting in standard form gives \(2x^2+0x-18=0\). This is written as \(2x^2-18=0\).
Exam Tip
मानक रूप में रखने पर \(2x^2+0x-18=0\) मिलता है। इसे \(2x^2-18=0\) लिखते हैं।
