Giai bat phuong trinh sau (x-1)(2x+3)<x(2x+1)-1
giai cac phuong trinh sau
(x-1)3+(2-x)(4+2x+x2)+3x(x+2)=17
giai bat phuong trinh sau: (5x-2/3)-(2x2 - x)/2 >= [x(1-3x)] /3 - (5x)/4
giai phuong trinh sau
9x^2-1= (3x+1) (2x-3)
Giai phuong trinh (2x + 3)(x+2 )^2(2x+5) = 3
giai phuong trinh x^2+2x+3=(x^2+x+1)(x^4+x^2+4)
Giai bat phuong trinh sau
\(\frac{2x+1}{x-3}\)>1
Giai phuong trinh lop 8
