Putting values
<h3>
Answer: (ab - c)(ab + c)</h3>
===================================================
Work Shown:
a^2b^2 - c^2
(ab)^2 - c^2
(ab - c)(ab + c)
In the last step, I used the difference of squares factoring rule.
The answers are in slope-intercept form, so you can see that the slope (coefficient of x) is only correct for choices b and c.
When you substitute x=3/2 into those equations, you find that b gives y=6 (correct) and c gives y=0 (incorrect).
The appropriate choice is ...
... b.) y = 2x+3
