{-1,7}
Find factors of -99 which sum to -2. Solution appears to be 9 and -11 (x + 9)(x - 11)
y squared minus 9 (y*y)- 9 cannot be solved because there is no given value for 9.
9 minus 8
-8.
It is: 9-4 = 5
3 - 3 squared = 6 * * * * * NO! 3 - 3 squared = 3 - 9 = -6
25x-32 = 7 25x-9 = 7 25x = 7+9 25x = 16 x = 16/25
