factor completely: 3x^2(4x^2+1)^8 + 64x^4(4x^2+1)^7
\n" ); document.write( "------------------
\n" ); document.write( "There is a common factor in the two terms.
\n" ); document.write( "It is x^2(4x^2+1)^7
\n" ); document.write( "-----------------------------
\n" ); document.write( "So factor the two terms to get these two factors:
\n" ); document.write( "x^2(4x^2+1)^7[3(4x^2+1) + 64x^2]
\n" ); document.write( "---
\n" ); document.write( "Simplify the 2nd factor to get:
\n" ); document.write( "---
\n" ); document.write( "x^2(4x^2+1)^7[12x^2 + 3 + 64x^2]
\n" ); document.write( "----
\n" ); document.write( "x^2(4x^2+1)^7[76x^2+3]
\n" ); document.write( "---
\n" ); document.write( "[(4x^2+1)^7][76x^4+3x^2]
\n" ); document.write( "================================
