You can put this solution on YOUR website! How do I solve this?
(a-1) (a-10)
----------------------
To multiply you use FOIL to get:
a^2-11a+10
--------
To solve it you must have an equation:
If (a-1)(a-10) = 0
then either a-1 is zero or a-10 is zero.
---
Solving:
If a-1 = 0, a = 1
If a-10=0, a = 10
=====
Conclusion:
Either a = 1 or a = 10
