(x+a)(x+b)(x+c)

= [(x+a)(x+b)](x+c)

= [x²+(a+b)x+ab](x+c)

= [x²+(a+b)x+ab]x+[x²+(a+b)x+ab]c

= x³+(a+b)x²+abx+x²c+(a+b)cx+abc

=x³+(a+b+c)x²+(ab+bc+ca)x+abc
Học tốt nha!!!!!!!!!

Rút gọn à bn ?

\(\left(x+a\right)\left(x+b\right)\left(x+c\right)\)

nó còn 100 chân

nó còn 99 chân vì nó lấy 1 chân bịt mũi

nó chỉ con 99 chân vì nó lấy 1 chân bịt mũi 

\(M=\sqrt{\dfrac{\left(11+\sqrt{96}\right)^2}{121-96}}+\sqrt{\dfrac{\left(11-\sqrt{96}\right)^2}{121-96}}\\ M=\dfrac{11+\sqrt{96}}{5}+\dfrac{11-\sqrt{96}}{5}=\dfrac{22}{5}\)

\(D=\dfrac{2}{\sqrt{3}-1}-\dfrac{3}{2-\sqrt{3}}-\dfrac{6}{3-\sqrt{3}}\)

\(=\sqrt{3}+1-6-3\sqrt{3}-3-\sqrt{3}\)

\(=-8-3\sqrt{3}\)
