Question

how do I do this :'(

Answer 1

-14sqrt6

break up the radicand into a product of known factors of its self.

Answer 2

294÷ 6 shows that 6(49)= 294. The square root of 49 is 7, so you can remove the 49 from inside the square root and multiply it by the -2 outside the root to get -14. that leave only the 6 inside the square root, so your answer is -14√6
