Answer:
Step-by-step explanation:
Student 2 is right. One way to factor equations is to find the greatest common factor, and take it out of the parentheses.
Let's "dissect" the equation:
6a -2b ---- when working with polynomials, you can have a variable as GCF. But in this case, there is no common variable between the two numbers. However, both number are multiples of 2, which is going to be our GCF> Divide both terms by 2, 6a/ 2 = 3a; -2b/2 = -b. So, we can rewrite our equation as follows: 2(3a - b).

Step-by-step explanation:
<u>Step 1: Define</u>
4a - 2
a = 5
<u>Step 2: Evaluate</u>
- Substitute in <em>a</em>: 4(5) - 2
- Multiply: 20 - 2
- Subtract: 18
x > -1
-2x+5 < 7
-2x<2
Now since you divide by (-1) to get positive 2,you need to flip the sign
(-2)/(-1)= 2 2/(-1)=-2
SO
2x>-2
x > -1
To check the solution do not replace the x by -1 because it shouls be more than -1 (You can choose 0,1,2,3....)
Example choose x=3
-2x3+5<7
-6+5<7
-1<7
