a)x2-x=-2x+2

b)4x2+4x+1=x2

Giải phương trình :

a, (3x-7)2 - 4(x+1)2 = 0

b, (x+1)4 + (x+3)4 = 82

tìm x biết

\(9\left(x+2\right)-3\left(x+2\right)=0\)

\(x\left(x+5\right)+\left(x-3\right)\left(x+5\right)=0\)\(3x^2+6x=0\)

\(2\left(2x-5\right)-3x=0\)

\(\left(x-1\right)^2+x\left(5-x\right)=0\)

\(\left(2x-3\right)\left(2x+3\right)-\left(x+5\right)^2-3\left(x-1\right)\left(x+2\right)\)=0

\(\left(2x-1\right)^2-45=0\)

\(2x^2-6x=0\)

giúp vs can gap

(8x-7)(8x-5)(2x-1)(4x-1)=9

giai cac pt sau:

2x^2-5x+2=0

3x^2-7x-20=0

x^3+x^2+4=0

x^3-5x^2+8x-4=0

a) (x-3)³ + (x+1)³= 8(x-1)³

b)x⁴ - 4x² + 12x - 9 = 0)

c)x\(^5\)=x⁴ +x³ + x² + x + 2

\(\left(x+2\right)^2+\left(x-1\right)\left(x+3\right)=2\left(x-4\right)\left(x+4\right)-3\)

Giúp mk với!!!

Giải các phương trình sau:
