= \frac{1}{4} (2 x - a) (2 x - 5 a) = \frac{1}{4} (4 x^{2} - 10 a x - 2 a x + 5 a^{2})

= \frac{1}{4} (4 x^{2} - 12 a x + 5 a^{2}) = x^{2} - 3 a x + \frac{5}{4} a^{2} .

x^{2} - \frac{5 x a}{2} - \frac{x a}{2} + \frac{5 a^{2}}{4}

x^{2} + \frac{5 a^{2}}{4} - \frac{6 a x}{2}

\frac{4 x^{2} + 5 a^{2} - 12 a x}{4}
