Answer: -3

Step-by-step explanation:

(1 + √5) − (4 + √5)

Rewrite expression to distribute negative:

(1 + [tex]\sqrt{5}[/tex]) - 4 -[tex]\sqrt{5}[/tex]

We see the following in the expression above:

1 - 4 = -3

[tex]\sqrt{5}[/tex] - [tex]\sqrt{5}[/tex] = 0

So the final answer is -3.

negative three sqrt5 cancels so it just becomes 1-4 which is -3
