Answer:
The x-intercepts are
and
.
Step-by-step explanation:
We are given the equation

Begin by dividing both sides of the equation by 2:

Next, take the square root of both sides. Remember that there are two solutions to a square root, the positive and the negative root:

Split the equation into two based on the two solutions:


Solve each equation by subtracting 1 from both sides:

Since the x-intercepts are the solutions to a quadratic, we know the solutions are (2,0) and (-4,0).
-4n + 7 + 2n = 1
First, simplify -4n + 7 + 2n to -2n + 7. / Your problem should look like: -2n + 7 = 1
Second, subtract 7 from both sides. / Your problem should look like: -2n = 1 - 7
Third, simplify 1 - 7 to -6. / Your problem should look like: -2n = -6
Fourth, divide both sides by -2. / Your problem should look like: n =
Fifth, simplify

to

/ Your problem should look like: n =
Sixth, simplify

to 3. / Your problem should look like: n = 3
Answer:
n = 3 (B)
