Level 2: Consider that x= -4/5 and x= 5. Find the value of M. (4x+5)(-mx+9)=0
m = 9/5
m=5/9
m=36x+45/4x2+5x

Level 4 : Solve for x. x^2+9x-10=0
x= -1 and x= -10
x= 1 and x= -10
x= 10 and x= -1
x= 10 and x = 1

Level 2: Consider that x=2 and x=7. Find the value of M. (x-2)(mx+5)=0.
m= -10
m= 7/-5
m=-5/7
m= 35

Level 3: (x-2)²- 81 = 0
x=\sqrt{81}+2
x=\frac{\sqrt{2}}{81}
x=\frac{\sqrt{81}}{2}
x=11 and x=-7
