Answer:
x = ±4√3
Explanation:
Given: x² = 48, find x. Note that we must take the square root of both sides, and that there are 2 roots (solutions) because this is a second order equation.
√x² = ±√48
48 is not a perfect square, but it does factor into 16 (a perfect square) and 3 (not a perfect square).
Thus, x = ±4√3 (the last answer choice)
