Tìm GTNN \(T=\sqrt{x^2-x+2}+\sqrt{x^2+x+2}\)

\(\sqrt{2020x-2019}+2019x+2019=\sqrt{2019x-2020}\)

Cho a, b, c là các số không âm thoả :

\(\sqrt{a}+\sqrt{b}+\sqrt{c}=\sqrt{3}\) và \(\sqrt{\left(a+2b\right)\left(a+2c\right)}+\sqrt{\left(b+2a\right)\left(b+2c\right)}+\sqrt{\left(c+2b\right)\left(c+2a\right)}=3\)

Tính giá trị biểu thức \(P=\left(2\sqrt{a}+3\sqrt{b}-4\sqrt{c}\right)^2\)
