Question

Question below is followed by two statements, labelled (A) and (B). Decide whether the data given in the statements is sufficient for answering the question.

Given****Information	Column A	Column B
x = -2	3x2+2x-1	x3+2x2+1

• A. The two quantities are equal
• B. The quantity in column B is greater
• C. The quantity in column A is greater
• D. The relationship cannot be determined from the information given.

Answer 1

Answer: (C)

The quantity in column A is greater

Answer 2

$X = -2$
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
