\"Solve the following equations

\n" ); document.write( "(ii) -5x2 = -500\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3 - 4x² = -85
\n" ); document.write( "-4x² = -88 {subtracted 3 from both sides}
\n" ); document.write( "x² = 22 {divided both sides by -4}
\n" ); document.write( "x = ±√22 {took square root of both sides}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-5x² = -500
\n" ); document.write( "x² = 100 {divided both sides by -5}
\n" ); document.write( "x = ±10 {took square root of both sides}
