(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!!!!!!!!!

\(M=\sqrt{\dfrac{\left(11+\sqrt{96}\right)^2}{121-96}}+\sqrt{\dfrac{\left(11-\sqrt{96}\right)^2}{121-96}}\\ M=\dfrac{11+\sqrt{96}}{5}+\dfrac{11-\sqrt{96}}{5}=\dfrac{22}{5}\)
có nhìn rõ đâu mà làm??:)
Bn cho phóng to thêm tý
