Express (x+4)^2 as a trinomial in standard form
To expand (x+4)^2 as a trinomial in standard form, we can use the formula for expanding (a+b)^2, which is a^2 + 2ab + b^2.
In this case, a = x and b = 4. So, we can substitute these values into the formula to get:
(x+4)^2 = x^2 + 2(x)(4) + 4^2
Simplifying, we have:
(x+4)^2 = x^2 + 8x + 16
Therefore, (x+4)^2 can be expressed as the trinomial x^2 + 8x + 16 in standard form.
