The Correct Option is C
Solution and Explanation
\(X = -2\)
Column A:
\(\Rightarrow\;\)\(3x^2+2x-1\)
\(\Rightarrow\;\)\(3\times (-2)^2+2(-2)-1\)
\(\Rightarrow\;\)\(12-4-1\)
\(\Rightarrow\;\)\(7\)
Column B:
\(\Rightarrow\;\)\(x^3+2x^2+1\)
\(\Rightarrow\;\)\((-2)^3+2(-2)^2+1\)
\(\Rightarrow\;\)\(-8+8+1\)
\(\Rightarrow\;\)\(1\)
So, Quantity A > Quantity B
The correct option is (C): The quantity in column A is greater
