1. Use the FOIL (first, outside, inside, last) method:

F: x*x=x^2

O: x*-2=-2x

I: 3*x=3x

L: 3*-2=-6

x^2-2x+3x-6

<em>*Combine like terms*</em>

x^2+x-6

2. Look for the greatest common factor (GCF) of 15 and 5.  It is 5 (15/5=3 and 5/5=1)

5(3x+1)

3. You want to find two numbers whose product is 6 and whose sum is -5.  -3 and -2 complete these requirements.

(x-3)(x-2)

4. Solve for x:

<em>*Add x to both sides*</em>

y+x=ab

<em>*Subtract y from both sides*</em>

x=ab-y

8. Plug in 0.5 for x and solve:

10-8(0.5)

10-4

6

10. <em>*Multiply both sides by 5*</em>

2x-3=20

<em>*Add 3 to both sides*</em>

2x=23

<em>*Divide both sides by 2*</em>

x=23/2

I did what I could.  Hope I could help!!
