Đặt phép chia ta được: \(2x^3-2x^2+x+a=\left(x+2\right)\left(2x^2-6x+13\right)+a-26\)
Để \(2x^3-2x^2+x+a\)chia hết cho \(x+2\)thì \(a-26=0\Leftrightarrow a=26\).

tim a de x^4+ax^2+1 chia het cho x^2+2x+1
Tim x thuoc z de:
a, x3 - 3x2 - 3x - 1 chia het cho x2 + x + 1
b, x3 - x2 + 2x + 7 chia het cho x2 + 1
tim a,b de A chia het cho B
\(1.A=8x^2+a+3x^3-5+2x^2:B=3x+1.\)
\(2.A=2x^3+b-3x^2-ax;B=-x-1+x^2\)
\(3.A=100x+2x^3-3x^2-99x+a;B=x+2\)
