(1 point) Find a basis of the subspace of [R4 defined by the equation 311 + 7x2 6x3 + 51;; = 0. Answer: EEE To enter a basis into WeBWorK, place the entries of each vector inside of brackets, and enter a list of these vectors, separated by commas. For instance, if your basis is 1 1 2 , 1 , then you would enter [1 ,2,3].[1,1,1] into the answer blank. 3 1
