Answer 1

The base of the triangle is x^2 + 2x + 4.
The height of the triangle is 2x^2 + 2x + 6.

Do you know the formula for the area of a triangle?

Answer 2

I think it's C, is that correct?

Answer 3

Disregard what I wrote a moment ago. Apparently I don't know the formula for area of a triangle xD

Area = 1/2 * Base x Height

So you can literally multiply those entire things together:
Area = (1/2) * (x^2 + 2x + 4) * (2x^2 + 2x + 6)

It's not C. Give it a shot and I'll help you through it.

...And in the end you get x^4+3 x^3+9 x^2+10 x+12
