Please explain to me step by step how to come to the final answer for the following equation:
\n" ); document.write( "What you wrote is not an equation, lets assume you mean
\n" ); document.write( " $\"2x%5E4-128=0\"$
\n" ); document.write( "divide through by 2, and you have
\n" ); document.write( " $\"x%5E4+-+64+=+0\"$
\n" ); document.write( "Factors to
\n" ); document.write( " $\"%28x%5E2-8%29%28x%5E2%2B8%29=+0\"$
\n" ); document.write( "the real solutions
\n" ); document.write( " $\"x%5E2+=+8\"$
\n" ); document.write( " $\"x+=+%2Bsqrt%288%29\"$ = $\"2%2Asqrt%282%29\"$
\n" ); document.write( "and
\n" ); document.write( " $\"x+=+-sqrt%288%29\"$ = $\"-2%2Asqrt%282%29\"$ \n" ); document.write( "

\n" );
