What is the simplified version of <img src="https://tex.z-dn.net/?f=%282%5Csqrt%7B5%7D%2B3%29%28%5Csqrt%7B5%7D-1%29" id="TexForm
Tpy6a [65]

ANSWER

EXPLANATION

We want to simplify:

(2\sqrt{5}+3)(\sqrt{5}-1)

Recall the distributive property;

(a+b)(c+d)=a(c+d)+b(c+d)

We apply this property to get,

2\sqrt{5}(\sqrt{5}-1) + 3(\sqrt{5}-1)

We expand to get,

2 \times 5-2 \sqrt{5} + 3\sqrt{5}-3

This simplifies to,

10 + \sqrt{5}-3

The simplest form of the given expression is:

7 +  \sqrt{5}
