{46\left(\dfrac{5}{6}x-\dfrac{5}{3}z\right)\left(\dfrac{6}{5}x-\dfrac{3}{5}z\right) = 46\left(\dfrac{5}{6}x\cdot\dfrac{6}{5}x+\dfrac{5}{6}x\cdot\left(-\dfrac{3}{5}z\right)-\dfrac{5}{3}z\cdot\dfrac{6}{5}x-\dfrac{5}{3}z\cdot\left(-\dfrac{3}{5}z\right)\right) = 46\left(x^2-\dfrac{1}{2}xz-2xz+z^2\right) = 46x^2-115xz+46z^2}
