Solving problems by factorization 3x (X-2) = X-2 to find X1 =? X2 =?

Solving problems by factorization 3x (X-2) = X-2 to find X1 =? X2 =?

First shift the term 3x (X-2) - (X-2) = 0
Take X-2 as a whole and merge the similar terms
(3x-1)(x-2)=0
3x-1 = 0 or X-2 = 0
x1=2,x2=1/3

Solving problems by factorization
On the four corners of a square open space with a side length of 12.8, a square subway block with a side length of 1.4m is set aside to build flower beds, and the rest is made into lawns?

12.8² -4*1.4²
=(12.8+2*1.4)(12.8-2*1.4)
=(12.8+2.8)(12.8-2.8)
=15.6*10
=156

Who can solve problems by factoring
1.4x power - X-1, the third power of 2. A + the second power of a - A-1 =?

2. The third power of a + the second power of a - A-1 =?
a^3+a^2-a-1
=a(a^2-1)+(a^2-1)
=(a^2-1)(a+1)
=(a+1)(a-1)(a+1)

Several factorizations of elementary one
Square of 1.9x + 6x + 2Y - (square of Y)
2. Square of x-2xy + square of Y-1
3. The square of x-2xy + y-2x + 2Y + 1
4. Square of x-2y-4y + x = () + () = () ()
5.4A's Square - B's Square - 4C's square + 4bc = () - () = () ()

1.(3x+y)(3x-y+2)
2.(x-y+1)(x-y-1)
3. The square of (x-y-1)
4. (x + 1.5) square - (2Y + 1.5) square = (x + 2Y + 1) (x-2y)
5. Square of (4a) = (4a + 2C-B) (4a-2c + b)
