Bài 2: 

a: \(\Leftrightarrow4x^2-20x+25-4x^2+12x=0\)

=>-8x=-25

hay x=25/8

1. 

a) x (x - 5) + (x + 3)(x - 3)=

= x^2 - 5x + (x + 3)(x - 3)

= x^2 - 5x + x^2 - 9

= x^2 + x^2 - 5x - 9

= 2x^2 - 5x - 9.

b. không thể nhìn thấy hết bài được. Nó bị mất dấu!!

c. (20x^2 + 7x - 6) : (5x - 2)

= (5x - 2) (4x + 3) : (5x - 2)

= 4x + 3.

2. 

a. (2x - 5)^2 - 4x (x - 3)= 0

                       -8x + 25= 0

                -8x + 25 - 25= 0 - 25

                               -8x= -25

                          -8x : 8= -25 : 8

                                 x = 25/8

Vậy x= 25/8

b. 2(x - 5) - x^2 - 5x= 0

                        -10x= 0

              -10x : (-10)= 0 : (-10)

                              x= 0

Vậy x= 0

c. Lí do cũng giống câu b bài 1.
