.
1.Simplify: (x - 2)(x + 3)
----------------
(x - 3)(x - 2)
2.
What are the restrictions on the variable in: (x - 2)(x + 3)
----------------
(x - 3)(x - 2)
3.
Simplify: a2 - a - 12
--------------
a2 - 16
4.What are the restrictions on the variable in: a2 - a - 12
--------------
a2 - 16
5.Simplify: 6x2 - 3x - 18
-----------------
(3x + 6)(3 + 2x)

6.What are the restrictions on the variable in: 6x2 - 3x - 18
-----------------
(3x + 6)(3 + 2x)
7.
Simplify: 3x2 + 2x - 8
----------------
12 - 5x - 3x2
8.
What are the restrictions on the variable in: 3x2 + 2x - 8
----------------
12 - 5x - 3x2

1) (x - 3)(x - 2)
2) (x - 3)(x - 2)
3) a2 - 16
4)a2 - 16
5)(3x + 6)(3 + 2x)
6) (3x + 6)(3 + 2x)
7) 2x-2
8)12-5x-3x2

1. X^2+x-6
And x^2-5x+6
2. don't know watchya mean by restrictions. Never done tht in math.
3. (a-4)(a+3)
And (a+4)(a-4)
4. Idk
5. 6x^2-3x-18 so (6x)^2-3(6x)-(18)(6) and so (6x-12)(6x+9) divide first parenthesis by 6 and the other by 1 so ur answer is (x-2)(6x+9).
