a) tron g phep chia mot so tu nhien cho 6,so du co the bang bao nhieu?

b) viet dang tong quat cua so tu nhien chia het cho 4, cho 4 du 1.

Mot da thuc P(x) chia cho\(x^2+x+1\) du \(1-x\)

va chia cho \(x^2-x+1\) du \(3x+5\) 

Tim so du cua phep chia P(x) cho \(x^4+x^2+1\)

cho da thuc P(x) thoa man:khi chia cho x-3 du 17;khi chia cho x-1 du 3.Tim so du trong phep chia P(x) cho x^2-4x+3

a) x2(x - 5) + 5 - x = 0; b) 3x4 - 9x3 = -9x2 + 27x;

c) x2(x + 8) + x2 = -8x; d) (x + 3)(x2 -3x + 5) = x2 + 3x.

Cau 1:

Tim x, biet:  1-4+7-10+.............-x=-75

Cau 2:

Cho x1, x2, x3, x4, x5 thuộc Z

Biết x1+ x2 + x3 + x4 + x5=0

và x1 + x2=x3+ x4= x4 + x5 =2

Tinh x3, x4 , x5

Cau 3:  Tim x biet

(x+7+1) chia het cho (x+7)

Chia da thuc f(x) cho da thuc (x+1) co so du la 5. Chia da thuc f(x) cho da thuc \(x^2+1\) co so du la 2x+3. Tim so du trong phep chia da thuc ?
