Question

multiply.
(sqrt7)(-6sqrt7 + 4)

Answer 1

-38??

Answer 2

\[\Large \sqrt{7}\left(-6\sqrt{7}+4\right)\]



\[\Large \sqrt{7}\left(-6\sqrt{7}\right)+\sqrt{7}\left(4\right)\]



\[\Large -6\sqrt{7*7}+4\sqrt{7}\]



\[\Large -6\sqrt{49}+4\sqrt{7}\]



\[\Large -6\left(7\right)+4\sqrt{7}\]



\[\Large -42+4\sqrt{7}\]

So \[\Large \sqrt{7}\left(-6\sqrt{7}+4\right) = -42+4\sqrt{7}\]
