(x-2)^3 = ( 2x+1)^3
\(\sqrt{x+2+3\sqrt{ }2x-5}+\sqrt{x-2-\sqrt{ }2x-5}=2\sqrt{2}\) 2\(\sqrt{2}\) giai phuong trinh
giai phuong trinh x^2+2x+3=(x^2+x+1)(x^4+x^2+4)
Giai bat phuong trinh sau (x-1)(2x+3)<x(2x+1)-1
Giai phuong trinh lop 8
3(2-x)+1=4-2x)
Giai phuong trinh (2x + 3)(x+2 )^2(2x+5) = 3
giai phuong trinh (x2 + 3x-4)3 + (2x2-5x+3)3 = (3x2 -2x-1)3
giai cac phuong trinh sau
