Diagonalize the quadratic form by finding an orthogonal matrix Q such that the change of variable x = Qy transforms the given form into one with no cross-product terms. Give Q and the new quadratic form, f(y). (Assume y = Y2 Enter your answer in the form (Q, A(y)) = ([[row 1], [row 2], [row 3]], A(y)) where each row is a comma-separated list and f(y) is in terms of y, , V2, and y3.) 7X 1 2+ x 7 - 2+ X3 2 + 8x,X, + 8X,X3 - 16X,X3 (Q, f(y) ) =\fDiagonalize the quadratic form by finding an orthogonal matrix Q such that the change of variable x = 011 transforms the Y1 Y2 answer in the form (Q, FWD = [[[rew 1], [row 2]], yjj, where each row is a commaseparated list and ffy) is in terms of y1 and V2.) given form into one with no crass-product terms.
