Answer:

Step-by-step explanation:
To calculate the result of that mutiplication you have to firs evaluate the first term of the second function multipying the whole first function, woudl be like this:

Now that you have this, you multiply the second term from the second function to obtain:

Now you just have to add both results:

+ 
And the result of the sum would be:
