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).
