giai pt
3x-7can x +4 =0
Giai pt \(x^2-5x-2\sqrt{3x}+12=0\)
Giai pt sau:
1/x^2-3x+2 +1/x^2-5x+6 +1/x^2-7x+12 =2(Tất cả =2 nhé!)
giai pt :3\(x^2\)- 5x- 2=0
giai pt \(\sqrt{2x^2^{ }+5x+12}+\sqrt{2x^2+3x+2}=x+5\)
cho P(x)=(x^2+5x-2)+(1/x^2+5/x-2)
a,Giai pt P(x)=0
b,Với x>0,tìm Min của P(x)
Giai pt sau : \(4\left(x^2+1\right)^2-\left(x^2-5x-2\right)^2=0\)
Giai PT
\(x^4+\left(x+1\right)\left(5x^2-6x-6\right)=0\)
GIAI PT
\(X^3+2X^2+6X+3=4\sqrt{5X-1}\\\)
\(X+Y+12=4X+6\sqrt{Y-1}\)
