Elizabeth: The second quadratic factors to this set of factors...
(2x=1)(x+2)
The first is a bit more complicated..
2x^4+3x^3+a(x^2+x)+b
x^2(2x^2+3x)+a(x^2+x)+b
x^2( x^2(2+a)+x(3+a))+ b
and I can not see it going further without some numeric value for a or b.
找A和B从2x^4+3x^3+a(x^2+x)+b,2x^2+3x-2是个因式。谢了！
