If (p(x)=(k-3)x^4+2x^2-5) must be exactly a quadratic polynomial in (x), what should be the value of (k)?यदि (p(x)=(k-3)x^4+2x^2-5) को (x) में ठीक द्विघात बहुपद होना है, तो (k) का मान क्या होना चाहिए?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (3)(3)
For exactly quadratic, the coefficient of (x^4) must be zero and the coefficient of (x^2) must remain non-zero. From (k-3=0), we get (k=3).ठीक द्विघात के लिए (x^4) का गुणांक शून्य होना चाहिए और (x^2) का गुणांक अशून्य रहना चाहिए। (k-3=0) से (k=3) मिलता है।
