We are given the equation

2 x^{2} + 10 x = 8 x + 2 x^{2}

. Decide which of the following equations has the different set of roots than the given equation has, i.e. choose the equation which is not equivalent to the given equation.

2 x + 10 = 8 + 2 x

10 x = 8 x

2 x^{2} + 2 x = 2 x^{2}

x^{2} + 5 x = 4 x + x^{2}
