So, letP(x)=ax2+bx+c ThenP(x)+P(2x)=5x2−18⇒ax2+bx+c+4ax2+2bx+c=5x2−18⇒5ax2+3bx+2c=5x2−18⇒5a=5,3b=0 and 2c=−18⇒a=1,b=0 and c=−9∴P(x)=x2−9and , Hence limx→3 P(x)x−3=limx→3 x2−9x−3=limx→3 (x+3)=6 Related content Class 9 Science MCQ Chapter 12 Sound CBSE Class 12 English MCQ with Answers (Flamingo & Vistas) CBSE Class 7 Science MCQ Questions with Answers CBSE Class 12 Subject Wise MCQ 2024-25 ICSE Class 10 Toppers List 2024 Available Tenses Worksheet for Class 10 CBSE Class 7 Science Chapter 4 Heat MCQ Questions with Answers Nephron Diagram Class 10 CBSE Class 7 Science Chapter 2 Nutrition in Animals MCQ with Answers Rabindranath Tagore Jayanti 2024
