Final answer:
To solve the quadratic equation u² = 4, you can use the Square Root Property to take the square root of both sides of the equation and solve for u.
Step-by-step explanation:
To solve the quadratic equation u² = 4 using the Square Root Property, we take the square root of both sides:
√(u²) = ±√4
u = ±2
So the solutions to the equation are u = 2 and u = -2.
