Factor Completely. y^4 + 3y^3 - 5y^2 - 15y
\n" ); document.write( ":
\n" ); document.write( "Factor out y^3 and 5y and you have:
\n" ); document.write( "y^3(y + 3) - 5y(y + 3)
\n" ); document.write( ":
\n" ); document.write( "Factor out (y + 3)
\n" ); document.write( "(y^3 - 5y) (y + 3)
\n" ); document.write( ":
\n" ); document.write( "also can factor out y:
\n" ); document.write( "y(y^2 - 5)(y + 3)
\n" ); document.write( "
