giai Pt (x+1)^6 + (x-1)^6 =2
giai pt (x+1)(x+2)(x+5)(x+10)=10x^2
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:\(\sqrt{\left(5-2\sqrt{6}\right)^x}+\sqrt{\left(5+2\sqrt{6}\right)^x}=10\)
Giải phương trình (x – 2)(x + 1)(x – 5)(x + 6) = 336
Giai pt: \(\sqrt{\left(5-2\sqrt{6}\right)^x}+\sqrt{\left(5+2\sqrt{6}\right)^x}=10\)
giai pt: x^2+6x+11=(x+6)*√(x^2+11)
giai pt: \(5x+19=2\sqrt{x-1}+4\sqrt{x+2}+6\sqrt{2x+5}\)
giai he pt giup mk voi : (xy+y^2)(x+y)=-6 va x(y+1)=-1
