Answer: $\bold{\dfrac{7-3\sqrt5}{2}}$

Step-by-step explanation:

You did great until you expanded (3 - √5)². <em>You forgot the middle term</em>

$\dfrac{3-\sqrt5}{3+\sqrt5}\bigg(\dfrac{3-\sqrt5}{3-\sqrt5}\bigg)\\\\\\=\dfrac{(3-\sqrt5)(3-\sqrt5)}{(3+\sqrt5)(3-\sqrt5)}\\\\\\=\dfrac{9-3\sqrt5-3\sqrt5+5}{9-3\sqrt5+3\sqrt5-5}\\\\\\=\dfrac{14-6\sqrt5}{4}\\\\\\\text{Factor out a 2 from the numerator and denominator}\\=\dfrac{2(7-3\sqrt5)}{2(2)}\\\\\\=\large\boxed{\dfrac{7-3\sqrt5}{2}}$

Answer:

The answer would be a) 4-2g

Step-by-step explanation:

Multiplying by one half is like dividing by 2!

8/2 = 4

and

4/2 = 2

It can't be b because you can't add 4g+2

It can't be c because you can't completely remove the 8/4

It can't be d because you didn't actually distribute
