This problem ( opportunity) is really about attention to detail.

Mathematically, we need to use the distributive property.

2 (3g -4) = 6g -8

-(8g + 3) = -8g -3

Put em together:  6g – 8g definitely-2g. Look at all the answers:  they all have-2g

Put em together: -8 – 3. Here’s the decision point

-8 less 3 or you lose $8, you lose $3,  or you can use a number line!

That’s awesome…2 more points!!

We can already analyze the two graphs above for the zeros.
Notice how (2) crosses the x-axis at (-2,0) and (4,0) at the ‘dots’ on the x-axis so that’s not right as we are looking for zeros of -4 and 2 (close but opposite signs)>
Ok let’s check out (4)…
Notice how (4) crosses the x-axis at (-4,0) and (2,0)? :)

(If we had to check (1) and (3), we would put each equation into Y= and check out the graph and/or table but no need to do that this time around)

This is a reading question!!

How many college students were surveyed?  16 + 20 + 14 = 50
How many prefer classic rock? 14

14 out of 50 = 14/50
14/50 = x /100   or you can do 14 divided by 50 on your calculator

Read carefully!  Watch your signs!
The solution set means what values will make the equation true.
What values of x will make the equation 0?
With a factor of (x – 2), x =2 would make the equation equal to zero!
Similarly, a factor of (x – a), x = a will also make the equation zero!
That’s it, 2 more points!
