given that a^2-b^2 =1 evaluate A=2(a^6-a^6)-3(a^4+a^4)
find the remainder in the division ò x^30+x^4-x^1975+1 by x-1
fine the remainder in the division of \(x^{30}+x^4-x^{1975}+1\) by x-1
Áp dụng định lý Bézout (Số dư trong phép chia đa thức f(x) cho nhị thức x-a bằng giá trị của f(a), ta được: số dư là 1
x^30+x^4-x^1975+1=(x-1).Q(x)+R ( R là số dư)
lấy x-1=0 thế x=1 vào 1^30+1^4-1^1975+1=2 . vẬY SỐ DƯ LÀ 2

Find the remainder in the division of (x^2+x^9-x^(1945)+1) by x+1.
Given that A=1^n+2^n+.....+98^n, where n is an odd possitive number. Fine the remainder in the division of A by 5
Suppose f(x) is a polynomial of x.If f(x) has a remainder of 3 when it is divided by 2(x-1) and 2f(x) has a remainder of -4 when it is divided by 3(x+2).Thus when 3f(x) is divided by 4(\(x^2+x-2\)),the remainder is ax+b,where a and b are constants.Then a+b=...............
Giả sử f (x) là một đa thức của x.Nếu f (x) có 3 phần còn lại khi chia cho 2 (x-1) và 2f (x) có phần còn lại của -4 khi chia cho 3 ( x + 2) .Vì khi 3f (x) được chia cho 4 ( x 2 + x - 2 x2 + x-2), phần còn lại là ax + b, trong đó a và b là hằng số. Sau đó a + b = ...............

10) Đặt biểu thức là A
\(A=x^2-x+1\)
\(\Leftrightarrow A=x^2-2.x.\left(\frac{1}{2}\right)+\left(\frac{1}{2}\right)^2-\frac{1}{2}^2+1\)
\(\Leftrightarrow A=\left(x-\frac{1}{2}\right)^2+\frac{3}{4}\)
\(\left(x-\frac{1}{2}\right)^2\ge0\Rightarrow\left(x-\frac{1}{2}\right)^2+\frac{3}{4}\ge\frac{3}{4}>0\)
Vậy điền dấu lớn hơn
9) Đặt biểu thức là B
\(B=-x^2+x-1\)
\(B=-\left(x^2-x+1\right)\)
\(B=-\left(x^2-2.x.\left(\frac{1}{2}\right)+\left(\frac{1}{2}\right)^2-\left(\frac{1}{2}\right)^2+1\right)\)
\(B=-\left(\left(x-\frac{1}{2}\right)^2+\frac{3}{4}\right)\)
\(B=-\left(x-\frac{1}{2}\right)^2-\frac{3}{4}\)
\(\left(x-\frac{1}{2}\right)^2\ge0\Rightarrow-\left(x-\frac{1}{2}\right)^2\le0\Rightarrow-\left(x-\frac{1}{2}\right)^2-\frac{3}{4}\le-\frac{3}{4}< 0\)Vậy điền dấu bé
