Factoring and Zero Product Property Quiz
1. What is the slope of the line on the graph to
the right?
2. Please write an equation for the line passing
through the points (– 2, 3) and (6, – 1)
3. What is the slope of the line passing through the points
(–2, 4) and (–2, 9)?
4. The following problem is solved correctly, but the steps are out of order. Please
rewrite the solution so that the steps are in order.
2(x2 – 2x – 3) = 0
x–3=0
or
x+1=0
2x2 – 4x = 6
2x2 – 4x – 6 = 0
x=3
or
2(x – 3)(x + 1) = 0
x=–1
5. Please solve for x by factoring and using the zero product property.
a. 9x(3x – 7) = 0
d. 9x2 = 16
b. 5x2 + 15x = 0
e. 3x2 – 6x + 3 = 0
c. 4x2 – 9 = 0
f. 36x2 + 12x = – 1
Bonus:
Please graph the function
f(x) = – 3x + 1
with a domain of {– 3, – 2, 0, 1, 2}
