solomonzelman · Answer

$\large\color{blue}{ \rm  16x^2-81=0  }$

$\large\color{blue}{ \rm  16x^2=81  }$

$\large\color{blue}{ \rm  16x^2=9^2 }$

$\large\color{blue}{ \rm 4^2x^2=9^2 }$

$\large\color{blue}{ \rm (4x)^2=9^2 }$

$\large\color{blue}{ \rm 4x=± 9 }$

$\large\color{blue}{ \rm x=± 9/4 }$
