Answer: x=17

or is it........

x=-12

2. 5(x+3)-2x = -21

Answer: x=-12

3. 3x+3(1-x)= x-17

Answer: x=20

4. 2[1-3(x+2)] = -x

Answer: x= -2

Factor Completely:

1. x^2-12x+20

Answer: (x-2)(x-10)

2. x^2-x-20

Answer: (x-5)(x+4)

3. x^2-49

Answer: (x+7)(x-7)

4. 4x^2-5x-6

Answer: (4x+3)(x-2)

1. |2x-5|= 29

Answer: x=17

or is it........

**
2x = 29 + 5 = 34
x = 34/2 = 17
The others look ok.**
