Question

($x^2+4x+3$) can be visualised by the rectangle below. Identify the region depicting the constant term.

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

The length of the green coloured box is $x$ units and the width is (1+1+1) = 3 units. Hence, the area of the block = $3x$ square units.

The length of the purple coloured box is 1 unit and the width is (1+1+1) = 3 units. Hence, the area of the block = 3$\times$1 = 3 square units.

The length of the red coloured box is $x$ units and the width is $x$ units. Hence, the area of the block = $x^2$ square units.

The length of the brown coloured box is 1 unit and the width is $x$ units. Hence, the area of the block = $x$ square units.

We can see that purple colour box is depicting the constant term.
