1) (2x-1-(4x2-1)=0
3) (x-5)² -x(x+2)=5
5) (x-3)(x+3)=(x-5)²
7) (3x+1)² -9x (x-2)=25
2) (x+2)² -x(x-3)=2
4) (x-1)²+x(4-x)=11
6) (2x+1)-4x(x-1)=17
8) (3x-2) (3x+2)-9(x-1)x=0
9) (x+2)² - (x-2)(x+2)=0
10)
(x+2)-(x-3)(x+3)=-3
11)
13)
(3x+2)-(3x-5)(3x+2)=0 12) (x+3)-(x+2)(x-2)=4x+17
3(x-1)²+(x+5)(2-3x)=-25
14) (x+3)²+(x-2)² = 2x²
