Answer:
The area in standard polynomial form is x^2 + 6x + 8.
Step-by-step explanation:
Assume that your 2+X•X+4 is actually (2 + x)*(x + 4). Must use parentheses here to obtain the proper multiplicative result.
Using the distributive property of multiplication, we get
2x + 8 + x^2 + 4x, which simplifies to x^2 + 6x + 8. This is the desired polynomial in standard form.
