    if we could get them to have the same radicals, then its just like working with a like variable

    \[\sqrt{160}=\sqrt{16}\sqrt{10}=4\sqrt{10}\] \[\sqrt{90}=\sqrt{9}\sqrt{10}=3\sqrt{10}\] \[-4\sqrt{10}-3\sqrt{10}=(-4-9)\sqrt{10}=-13\sqrt{10}\]

    the other 2 im sure would simplify to a like radical of their own

    thats becasue I only worked out part of it to demonstrate how it would be done, you are spose to take the initiative to complete it or ask questions about anything that may be unclear.
