Sadly no, it is incorrect.

First step is to subtract '5p' from both sides. Then you must simplify 8p + 4 - 5p to 3p+4. Now you have to subtract 4 from both sides. Then simplify -14 - 4 to -18. After that step you divide both sides by -3 (which is -18/3). Simplify the fraction to a whole number which is 6. Add the format (-6 = p), <u>but don't forget to flip!</u>

Your answer is p = -6.

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}
