You can put this solution on YOUR website!
By \"grouping\" and factoring:
\n" ); document.write( "8x^3-12x^2+2x-3=0
\n" ); document.write( "(8x^3-12x^2)+(2x-3)=0
\n" ); document.write( "4x^2(2x-3)+(2x-3)=0
\n" ); document.write( "factoring out the (2x-3):
\n" ); document.write( "(2x-3)(4x^2+1)=0
\n" ); document.write( ".
\n" ); document.write( "setting each term to zero:
\n" ); document.write( "2x-3=0
\n" ); document.write( "2x=3
\n" ); document.write( "x=3/2
\n" ); document.write( "and
\n" ); document.write( "4x^2+1 = 0
\n" ); document.write( "4x^2 = -1
\n" ); document.write( "x^2 = -1/4
\n" ); document.write( "x = sqrt(-1/4)
\n" ); document.write( "x = +-(1/2)i
\n" ); document.write( ".
\n" ); document.write( "solution:
\n" ); document.write( "x = (3/2, (1/2)i, -(1/2)i}\r
\n" ); document.write( "
