If (q(x)=(c+5)x^3+(c-2)x^2+4x-1) must have degree (2), what condition is needed?यदि (q(x)=(c+5)x^3+(c-2)x^2+4x-1) की घात (2) करनी हो, तो कौन-सी शर्त चाहिए?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (c=-5)(c=-5)
For degree (2), the coefficient of (x^3) must be zero. From (c+5=0), (c=-5), and the (x^2) coefficient (-7) remains non-zero.घात (2) के लिए (x^3) का गुणांक शून्य होना चाहिए। (c+5=0) से (c=-5) और (x^2) का गुणांक (-7) अशून्य रहता है।
