x^2+√(x+2010)=2010
x≥-2010
√(x+2010)=t, t≥0; t^2=x+2010
he
x^2+t=2010(1)
t^2-x=2010(2)
(1)-(2)=>(x+t)(x-t+1)=0
x=-t=>-2010≤ x≤0
(1)=> x^2-x-2010=0
∆=1+2010.4=8041
x1=(1-√8041)/2(n)
x2=(1+√8041)/2(l)
t=x+1; x≥-1
(1)<=>x^2+x-2009=0
∆=8037
x3=(-1-√8037)/2(l)
x4=(-1+√8037)/2(n)
kl
x=(1-√8041)/2; (-1+√8037)/2

loi giai rat hoang trang
thuc su sai toan tap.
ko phai don gian sai do (+,-./)
ma sai co ban. (ban chat)

ban khong tin co dung may tinh nhap
x=(1+√8041)/2=> ??

or
f(x); x=(-1-√8037)/2=?
