solve4(x -2)^2=36 by using square roots.
\n" ); document.write( "4(x -2)^2=36
\n" ); document.write( "divide by 4
\n" ); document.write( "(x-2)^2=9
\n" ); document.write( "take the sqrt of both sides
\n" ); document.write( "x-2=±√9=±3 (note: in an equation, the sqrt of a number always has two roots, one plus and one minus. When not in an equation, by itself, the sqrt has one positive root.)
\n" ); document.write( "x=2±3
\n" ); document.write( "x=-1
\n" ); document.write( "or
\n" ); document.write( "x=5\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
