Question

Express ( x + 4 )∧2 as a trinomial in standard form.

Answer 1

x^2+8x+16

Explanation:

Assuming that is to the power of two

We can use special products to do this which states that the answer to this will be a^2+2ab+b^2 where the first value is a and the second value is b. So we just plug that in and do x^2+8x+16.

We can also just do (x+4)(x+4) and do that out but that takes more time and you'll get the same answer.

Let me know if you have any questions

Answer 2

Answer: x²+8x+16

Explanation:

(x+4)^2=(x+4)(x+4)

Now use distributive property to expand (x+4)(x+4):

(x+4)(x+4)=x²+4x+4x+4(4)

x²+4x+4x+4(4)=x²+8x+16
