I hope this helps

$\cfrac{5+3 \sqrt{5} }{ \sqrt{5} } =\cfrac{(5+3 \sqrt{5}) \sqrt{5} }{ \sqrt{5}* \sqrt{5} }= \cfrac{5 \sqrt{5}+15 }{5} = \cfrac{5 (\sqrt{5}+3) }{5} = \sqrt{5}+3$

The equation x 2 + 10 x + 25 = 0 has one solution.

Natalija [7]

Answer:

Yes

Step-by-step explanation:

X2+10x+25=0

So let's solve

10=5,5

25=5,5

So let's continue

X2+5x+5x+25

Let's factorise

X(x+5)+5(x+5)=0

(X+5)(x+5)=0

X+5=0

Substrate 5 from both sides

X=-5(twice)

So the answer is yes
