You can put this solution on YOUR website!
4x^(2)=20 IN THIS EQUATION, THE / SIGN STANDS FOR +- AND THE ~ SIGN STANDS FOR THE SQUARE ROOT OF SYMBOL.\r
\n" ); document.write( "\n" ); document.write( "Divide each term in the equation by 4.
\n" ); document.write( "(4x^(2))/(4)=(20)/(4)\r
\n" ); document.write( "\n" ); document.write( "Simplify the left-hand side of the equation by canceling the common factors.
\n" ); document.write( "x^(2)=(20)/(4)\r
\n" ); document.write( "\n" ); document.write( "Simplify the right-hand side of the equation by simplifying each term.
\n" ); document.write( "x^(2)=5\r
\n" ); document.write( "\n" ); document.write( "Take the square root of both sides of the equation to eliminate the exponent on the left-hand side.
\n" ); document.write( "x=\~(5)\r
\n" ); document.write( "\n" ); document.write( "First, substitute in the + portion of the \ to find the first solution.
\n" ); document.write( "x=~(5)\r
\n" ); document.write( "\n" ); document.write( "Next, substitute in the - portion of the \ to find the second solution.
\n" ); document.write( "x=-~(5)\r
\n" ); document.write( "\n" ); document.write( "The complete solution is the result of both the + and - portions of the solution.
\n" ); document.write( "x=~(5),-~(5)_x=2.24,-2.24 \n" ); document.write( "

\n" );
