Giai phuong trinh, bat phuong trinh sau:
x-3/x-2 + x-2/x-4 = 16/5x-4/5 - x + 4 > x/3 - x-2/2 Giai giup minh nhe. Cam on rat nhieu.bài 1 : giai các phuong trinh sau :
a, (9x^2-4) (x+1) = (3x+2) (x^2-1)
b, x^4+ x^3 +x +1=0
c,x^5 - 5x^3 +4x=0
giai phuong trinh:
a)2x(x+5)-(x-3)^2 = x^2 +6
b)(4x+7)(x-5)-3x^2=x(x-1)
Giai Phuong Trinh:
