$\"3x%5E2-8x%2B2=0\"$
\n" ); document.write( " $\"3x%5E2-8x%2B2=0\"$
\n" ); document.write( "Divide by 3 both sides
\n" ); document.write( " $\"3x%5E2%2F3-8x%2F3%2B2%2F3=0\"$
\n" ); document.write( " $\"x%5E2-8x%2F3%2B2%2F3=0\"$
\n" ); document.write( " $\"x%5E2-8x%2F3=-2%2F3\"$
\n" ); document.write( " $\"%28x%5E2-%282%29%281%29%28x%29%284%2F3%29%29=-2%2F3\"$
\n" ); document.write( "Add (4/3)^2 both sides
\n" ); document.write( "

\n" ); document.write( " $\"%28x-4%2F3%29%5E2=%28-2%2F3%2B16%2F9%29\"$
\n" ); document.write( " $\"%28x-4%2F3%29%5E2=%28%28-2%2A3%29%2B16%29%2F9%29\"$
\n" ); document.write( " $\"%28x-4%2F3%29%5E2=%28%28-6%2B16%29%2F9%29\"$
\n" ); document.write( " $\"%28x-4%2F3%29%5E2=10%2F9\"$
\n" ); document.write( "Take Square root both sides
\n" ); document.write( " $\"sqrt%28%28x-4%2F3%29%5E2%29=sqrt%2810%2F9%29\"$
\n" ); document.write( " $\"x-4%2F3=sqrt%2810%29%2F3\"$ or $\"x-4%2F3=-sqrt%2810%29%2F3\"$
\n" ); document.write( " $\"x=sqrt%2810%29%2F3%2B4%2F3\"$ or $\"x=-sqrt%2810%29%2F3%2B4%2F3\"$
\n" ); document.write( " $\"x=%284%2Bsqrt%2810%29%29%2F3\"$ or $\"x=%284-sqrt%2810%29%29%2F3\"$ \r
