Final answer:
The equation v² = 144 has two solutions, v = 12 and v = -12, which are obtained by taking the square root of both sides.
Step-by-step explanation:
To solve the equation v² = 144, we need to take the square root of both sides of the equation. the square root of 144 is 12, but since squaring a negative number also gives a positive result, there are two solutions to this equation: v = 12 and v = -12. Therefore, the simplified answer is that v can be either 12 or -12.
