Graph the solutions to the compound inequality and write the solution in interval notation. Use brackets or parentheses where appropriate. \( x \leq 9 \) or \( x \leq 2 \)

\( ( 4 x ^ { 4 } y ^ { 3 } ) ^ { \prime } + 0 - ( x ^ { - 5 } y ^ { - 2 } ) ^ { \prime } + ( 4 y ^ { 3 } ) ^ { \prime } \)

b) \( x^{2} y^{\prime \prime}-3 x y^{\prime}+4 y=x^{2} \) (bonus, +1.5 p ) Solve the DE

Use the Quadratic Formula to solve the quadratic equation. (Enter your answers as a comma-separated list.) \[ 9 x^{2}-6 x+226=0 \] \( x=\square \)

- \( g(t)=\sqrt{2 t-1} \)

Solve the equation. Check your solutions. (Enter your answers as a comma-separated list.) \[ \left(x^{2}-x-30\right)^{3 / 2}=125 \] \( x=\square \)
