giai phuong trinh
a , x(x+1)(x-1)(x+2)= 24
b , (x-4)(x-5)(x-6)(x-7) = 1680
giai phuong trinh
(x^2 + 1)^2 + 3x(x^2 + 1) + 2x^2 = 0
(x^2 - 9)^2 = 12x + 1
giai chi tiet gium nha
Giai Phuong Trinh:
a)2(x-2)+x-2=3(x-2)
b)4(1-x)+3x=1-x
c)3(x-2)+4(1-x)=-(6+x)
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
a) \(\frac{3}{2x-16}+\frac{3x-20}{x-8}+\frac{1}{8}=\frac{3x-102}{3x-24}\)
b) \(\frac{1}{3-x}+\frac{14}{x^2-9}=\frac{x-4}{3+x}+\frac{7}{3+x}\)
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
(x+1)2(x-2)+(x+1)2(x+2)=-24
giai cac phuong trinh sau
(x-1)3+(2-x)(4+2x+x2)+3x(x+2)=17
giai phuong trinh
1, (x-2)(x-1)(x-8)(x-4)=4x^2
2, (x^2+5x+6)(x^2+20x+96)=4x^2
3, 3(x^2+2x-1)^2-2(x^2+3x-1)^2+5x^2=0
