This exercise addresses the sum of two complex numbers in the Cartesian form.

Consider two complex numbers in the Cartesian form:

x_1 = \alpha_1 + j\beta_1
x_2 = \alpha_2 + j\beta_2

Fill the boxes with the values of the real and the imaginary parts of each complex number.

\alpha_1 =        \beta_1 =        \alpha_2=        \beta_2 =
