Note: , Note: Simplified method.

Note: 32*, note: , note, Convert decimals into false fractions is the easiest trick.

Solution: 3x 2-6x-x+2=0

3x^2-7x+2=0

x-2)(3x-1)=0

So x1 = 2 and x2 = 1 3

2.（2x-1)²-2（2x-1)=3

Solution: (2x-1) -2(2x-1)-3=02x-1-3)(2x-1+1)=0

2x=4 or 2x=0

So x1 = 2 and x2 = 0

3.(x -5x+1)(x -5x+9)+15=0 solution: (x -5x)+10(x -5x)+9+15=0x -5x)+10(x -5x)+24=0x -5x+4)(x -5x+6)=0

x-4)(x-1)(x-3)(x-2)=0, so x1=4, x2=1, x3=3, x4=24Solve equation 4 about xSolve the equation about x (x-a) = b(x -a) (where a, b is constant, b≠1) where a, b is constant, and b≠1).

Solution: (x-a) -b(x-a)(x+a)=0(x-a)-b(x+a)](x-a)=0

x-a-bx-ab)(x-a)=0

So x1=a, x2=(a+ab) (1-b).

Note: , Note: Simplified method.

Note: 32*, Note: , Description, Calculate the fraction of the decimal into a fake celery is the easiest trick, 1, candy1982114 Report.

32* Note family hidden: no simple calculation method I don't know if you have learned fractions, if not, then remember,,2, flexible change is enough, 3x 2-6x-x+2=0

3x^2-7x+2=0

x-2)(3x-1)=0

So x1 = 2 and x2 = 1 3

2.（2x-1)²-2（2x-1)=3

2x-1)²-2（2x-1)-3=0

2x-1-3)(2x-1+1)=0
