How about this?

$$\eqalign{
 \sigma_P^2 &= X_1^2 E\left[\left(R_1j - \bar{R}_1\right)^2\right] +
2X_1 X_2 E\left[\left(R_{1j} - \bar{R}_1\right)\left(R_{2j} -
\bar{R}_2\right)\right]\cr &\qquad + X_2^2 E\left[\left(R_{2j} -
\bar{R}_2\right)^2\right]\cr &= X_1^2 \sigma_1^2 + 2X_1 X_2
E\left[\left(R_{1j} - \bar{R}_1\right)\left(R_{2j} -
\bar{R}_2\right)\right] + X_2^2 \sigma_2^2\cr
}$$
