Answer:
(1 -2y)(1 +2y)
Step-by-step explanation:
The difference of squares is factored as ...
... a² - b² = (a -b)(a +b) . . . . . . . . a form you should keep handy
Here, you have a=1, b=2y, so your factored form is ...
... 1 -4y² = (1 -2y)(1 +2y)

Answer:
Step-by-step explanation:
- a. -9+2, in this case, it is -7 because you take the bigger number and subtract it by the lower number. If the bigger number is negative your answer will be negative, if the bigger number is positive it will be positive it is just really a basic subtraction problem just add the sign.
- b. In multiplication +++=+ ++-=- and a -+-=+ do your problem without thinking about the signs and then add the signs with the formula I showed you.
Hope this helps :)!
