Use the square root property to solve the equation. The equation has real number solutions. \[ (3 x+1)^{2}=8 \]

2imalify \( \frac{x^{2}-y^{2}}{x^{2} x y} \) \( \frac{y+2 x-3 y}{3 x-2 y}=4 \), evaluate \( 2 x y \) If \( z=\sqrt{x^{2}-y^{2}} \), express \( x \) interm 9 \( y \) and 2

\( \left\{ \begin{array} { l } { 2 x y - y = 7 } \\ { x - 5 y - 2 } \end{array} \right. \)

d the exact value of the solution to the equation \( 2 e^{2 x}-7 e^{x}-4=0 \)

ii) \( \frac{4 x^{2}+3 x+7}{x+1} \)
