Step-by-step explanation:

We know that, 2x - y + z = 0

                  let, 2x + z = y  ---- (eqn 1)

Consider,   4x² - y² + z² +4xz

                = 4x² + z² + 4xz - y²                      (Rearranging the terms)

                = (4x² + z² + 4xz) - y²

                = ( 2x + z)² - y²                              (Using a²+b²+2ab= (a+b)² formula)

                = (y)²-y²                                         ( From eqn 1)

                = 0

Thus, if 2x - y + z = 0 then 4x² - y² + z² +4xz=0
