4x-3=4-3x
<=> 4x+3x=4+3
<=> 7x=7
<=> x=1
Vậy phương trình có nghiệm bằng 1
4x - 3 = 4 - 3x
4x + 3x = 3 + 4
7x = 7
x = 7 : 7
x = 1
giai phuong trinh sau x^5-5x^4+4x^3+4x^2-5x+1=0
Giai phuong trinh: x(x+3)(x^2+3x+4)=-4
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
2x(8x - 1)^2 (4x - 1) = 9
(12x + 7)^2 (3x + 2)(2x + 1) = 3

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
giai phuong trinh:
a)2x(x+5)-(x-3)^2 = x^2 +6
b)(4x+7)(x-5)-3x^2=x(x-1)
3(1-2x)<= 4(5-3x/2)
