Get the Math and Points Jan 2017 CC Alg I Regents #7

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)

We can figure out the answer to this problem by studying the signs.

To get the “-” in 16x^2 – 36, we need a “+” and a “-” so when they are multiplied together they will equal a “-“.
Answer (1) has 2 negatives that when multiplied will equal a positive
Answer (3) has 2 negatives that when multiplied will equal a positive
Answer (4) has 2 positives that when multiplied will equal a positive
So find the one that has a positive and negative!  2 points :)
