Answer: (x+5)(x-3)2 = 0

Step-by-step explanation: To write this equation as a polynomial, you must multiply it out.

begin by squaring the binomial, and remember to express this as a trinomial (middle term will be -6x).

Then, to finish the job, multiply that trinomial by the factor x+5. Hope this will help you.

Answer:

16√3
-45+15i
√255
6√2 +3√10

Step-by-step explanation:

$-4i\sqrt{-48}=-4i\sqrt{(-1)(4^2)(3)}=(-4i)(4i)\sqrt{3}=16\sqrt{3}$

$(-5-5i)(3-6i)=-5(3-6i)-5i(3-6i)=-15+30i-15i+30i^2=-15-30+15i\\\\=-45+15i$

$\sqrt{3}\sqrt{5}\sqrt{17}=\sqrt{3\cdot 5\cdot 17}=\sqrt{255}$

$\sqrt{3}(\sqrt{24}+\sqrt{30})=\sqrt{3\cdot 24}+\sqrt{3\cdot 30}=\sqrt{6^2\cdot 2}+\sqrt{3^2\cdot 10}\\\\=6\sqrt{2}+3\sqrt{10}$

_____

The applicable identities are ...

$\sqrt{a^2b}=a\sqrt{b}\\\\i^2=-1$
