Answer:
-2
Step-by-step explanation:
In order to expand this, we need to use FOIL (first, outer, inner, last).
The first term for each expression is √3, so we multiply those together first:
(√3) * (√3) = 3
The outer term for the first expression is √3 and the outer term for the second equation is -√5, so multiply these next:
(√3) * (-√5) = -√15
The inner term for the first expression is √5 and the inner term for the second equation is √3, so multiply these:
(√5) * (√3) = √15
The last term for the first expression is √5 and the last term for the second equation is -√5, so finally, multiply these:
(√5) * (-√5) = -5
Now, add all these together:
3 + (-√15) + √15 + (-5) = 3 - 5 = -2
The answer is -2.
Hope this helps!
