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 phương trình :
3x - 4= 5 - 6x
( 2x - 3 )( x - 4 ) = 0
x3 - 7x 2 + x - 7 = 0
GIAI PHUONG TRINH:
x6+3x5+6x4+x3+3x+1=0
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: x(x+3)(x^2+3x+4)=-4
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
giai phuong trinh
1, -3x \(\ge\)\(\frac{1}{5}\)
giai bat phuong trinh
a,\(|2-x|+5=0\)
b, \(|3-2x|+x=0\)
c,\(2x-|x+4|=7\)
GIAI PHUONG TRINH
(X-5)*(X-3)-2*(3X-4)=(X-3)^2+!2
a, (3x-7)^2-4(x+1)^2=0
b,(x+1)^2.(x+2)+(x+1)^2.(x-2)=-24
