it doesn't it equals 4
0 minus negative 6 is equal to 6.
-6
=1
4
If: x^2 -5x +6 = 0 then x = 2 or x = 3
6/9-2/3=0
15 minus 6 divided by 2 is equal to 12.
17
Try to factor the left side and set each of the linear expressions equal to zero. 7x^2 +8x -12= 0 (7X-6)(X+2)=0 7X-6=0 X=6/7 X+2=0 X=-2
6 + -2 = 4
Negative 4 minus positive 2 is equal to negative 6.
if u mean if u minus 6 for 8 then no it equals 2
