Answer:

$(x+1-i)(x+1+i)$

Step-by-step explanation:

$(x+1-i)(x+1+i)\\\\=(x+1)^2 -i^2~~~~~~~~~~~~~;[a^2 -b^2 = (a+b)(a-b)]\\\\=x^2 +2x +1 -(-1)\\\\=x^2 +2x +1+1\\\\=x^2 +2x +2$

Answer:

$(f+g)(x)=3^x+4x+8$

if $f(x)=3^x+10$ and $g(x)=4x-2$ .

Step-by-step explanation:

We are given $f(x)=3^x+10$ and $g(x)=4x-2$ .

We are asked to find $(f+g)(x)$ .

$(f+g)(x)$ means $f(x)+g(x)$

$(f+g)(x)=(3^x+10)+(4x-2)$

You only have one pair of like terms, that is the constants.

$(f+g)(x)=3^x+4x+10-2$

$(f+g)(x)=3^x+4x+8$
