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!!
The correct answer is: [C]: " <span>15u^2^v</span><span> " .

1/4 dividend by 5/13 is the same as
1/4 multiplied by 13/5 it’s inverse
1 x13 / 4x 5 = 13/20
Look at it on the Internet
