Answer:
The square root function
sqrt(144) or √144 produces a single positive value, 12.
However if you have an equation
x² = 144, then you have two possible values for x, 12 and -12.
Two ways to look at it.
x² - 144 = 0
Difference of two squares
(x+12)(x-12) = 0
x = -12, 12
x² = 144
x = ±√144
x = ±12
x = -12, 12

ik the doesnt rlly make any sense but hope this helps
Answer:
9
Step-by-step explanation:
m = j^2 -7p
18 = j^2 -7(9)

81 = j^2
√81 = √j^2
9 = j
