$$ \begin{array}{ll}	ext { 57. } x^{2}=8 x-15 & 	ext { 58. } x^{2} \ 	ext { 59. } 5 x^{2}=20 x & 	ext { 60. } 3 x\end{array} $$

- **57:** $$ x = 3 $$ and $$ x = 5 $$ - **58:** Expression $$ x^{2} $$ - **59:** $$ x = 0 $$ and $$ x = 4 $$ - **60:** Expression $$ 3x $$

\( \begin{array}{ll}\text { 57. } x^{2}=8 x-15 & \text { 58. } x^{2} \\ \text { 59. } 5 x^{2}=20 x & \text { 60. } 3 x\end{array} \)
