Bạn Đức đố : " Bậc của đa thức \(M=x^6-y^5+x^4y^4+1\) bằng bao nhiêu ?"
Bạn Thọ nói : "Đa thức M có bậc là 6"
Bạn Hương nói : "Đa thức M có bậc là 5"

Đáp án: Bậc của đa thức là: Trả lời
Hệ số tự do của đa thức là: Trả lời
Hệ số cao nhất của đa thức là:
Tìm đa thức q(x) thỏa mãn
1. có 1 nghiệm bằng 0 và là đa thức bậc 3
2. Có 1 ngiệm là -1 và là đa thức bậc 5
Tìm bậc của đa thức 2x2 - 3x +
A(x)=x^3+2x^2+2x^3-1-2x^2+3x
B(x)=x^2-2x^3+4x-3
a)Thu gọn và sắp xếp các đa thức theo luỹ thừa giảm của biến và tìm bậc của đa thức
b)Tính A(x)+B(x),B(x)-A(x)
c)Đặt M=A(x)+B(x).Tính M(-3)
