factorise the following
\n" ); document.write( "1) 18x^2-96x+128
\n" ); document.write( "2[9x^2-48x+64]
\n" ); document.write( "2(3x-8)(3x-8)
\n" ); document.write( "--------------------
\n" ); document.write( "2) 45y^4z-80y^2z^3
\n" ); document.write( "5y^2z[9y^2-16z^2]
\n" ); document.write( "5y^2z(3y-4z)(3y+4z)
\n" ); document.write( "-------------------------
\n" ); document.write( "3) x^4+5x^3-7x^2-5x+6 given(x^2-1) is a factor.
\n" ); document.write( "Using synthetic division:
\n" ); document.write( "---
\n" ); document.write( "1)....1....5....-7....-5....6
\n" ); document.write( ".......1....6.....-1....-6..|..0\r
\n" ); document.write( "\n" ); document.write( "-1)....1.....5.....-6....|..0\r
\n" ); document.write( "\n" ); document.write( "Quotient: x^2+5x-6
\n" ); document.write( "=======================
\n" ); document.write( "Factored Form: (x-1)^2(x+1)(x+6)
\n" ); document.write( "=====================================
