2) Expand the expression: (x-1)(-49) = -49x + 49
3) Expand the expression: (x-8)(-9) = -9x + 72
Set both expressions equal to zero:
-49x + 49 = 0x = 49/49x = 1
-9x + 72 = 0x = 72/-9x = -8
Therefore, the solutions are x = 1 and x = -8.

3) Expand the expression: (x-8)(-9) = -9x + 72
Set both expressions equal to zero:
-49x + 49 = 0
x = 49/49
x = 1
-9x + 72 = 0
x = 72/-9
x = -8
Therefore, the solutions are x = 1 and x = -8.
