\n" ); document.write( "\"+40=%282X%2B8%29%284X%29%28X%29+\" x = 1 is a root, can expand to find the other two roots
\n" ); document.write( "\"+40=%282X%2B8%29%284X%29%28X%29+\" = \"+5=%28X%2B4%29%28X%29%28X%29+\" = x^3 + 4x^2 - 5
\n" ); document.write( "Using Synthetic Division to Find other two roots
\n" ); document.write( "1 1 4 0 -5
\n" ); document.write( " 1 5 5
\n" ); document.write( " 1 5 5 0
\n" ); document.write( " (x^2 + 5x + 5) \"x+=+%28-5+%2B-+sqrt%28+5+%29%29%2F%282%29+\"
\n" ); document.write( "X is -3.618, -1.382 , 1
