Solution 3.10: (3x + 1)² + 2²,     (2x - 1)² - 2²,     (3x - 2)²,     t² - (tx - t)²,(t = $\sqrt{2}$),     ($\sqrt{3}$)² - (2x + 1)²,     (x + ${\frac{1}{2}}$)² + ($\sqrt{7}$/2)²

$${\textstyle\frac{1}{2}}$$arcsin$${\frac{2x+1}{\sqrt{3}}}$$,        (2x + 1 = $$\sqrt{3}$$sin y)

$${\frac{1}{\sqrt{2}}}$$arcsin(x - 1),        (x - 1 = sin y)

$${\textstyle\frac{1}{3}}$$sinh^-1($${\textstyle\frac{1}{2}}$$(3x + 1)),        (3x + 1 = 2 sinh y)
