Find the missing term in the following problem:

$$\left(\displaystyle \frac{3x}{4}\, -\, \displaystyle \frac{4y}{3} \right )^2\, =\, \displaystyle \frac{9x^2}{16}\, +\, ..........\, +\, \displaystyle \frac{16y^2}{9}$$.

Simplify: $$(7m -8n)^2 + (7m + 8n)^2$$.

Simplify: $$3x(4x -5) + 3$$ and find its value for $$x =$$ $$\displaystyle \frac{1}{2}$$
