Extracted text: (2, 4, 0), the Gram-Schmidt process Given vị = (-1, 2, –1), v2 = (1, 7,1) and v3 allows us to construct an orthonormal basis {u1, u2, U3 } of R³ such that u¡ is a multiple of V1, u2 is a linear combination of vj and v2, and uz is a linear combination of v1, V2 and v3. Then u2 is equal to: O (1,1, 1) O (1,2, 0) (1:2'0뚜 이 O (0, 1, 0) o (-1, 2, –1) ㅇ 늘(1,0, 1)
