1. 5x2−8x=05x^2 - 8x = 05x2−8x=0

2. −3x2−6x=0-3x^2 - 6x = 0−3x2−6x=0

3. $2x(x-3)=x-3$

4. $2x(x-3)+5x-15=0$

5. (1+x)2−(x−1)2=0(1 + x)^2 - (x - 1)^2 = 0(1+x)2−(x−1)2=0

6. (x−2)2=(3x+5)2(x - 2)^2 = (3x + 5)^2(x−2)2=(3x+5)2

7. (6−9x)2=(5x−7)2(6 - 9x)^2 = (5x - 7)^2(6−9x)2=(5x−7)2

8. (x+1)2(x+2)=0(x + 1)^2(x + 2) = 0(x+1)2(x+2)=0

9. (3x−1)(3−x)2=0(3x - 1)(3 - x)^2 = 0(3x−1)(3−x)2=0
