The__ property allows an equation in one variable to be written as a system of equations.

The product equality property allows an equation in one variable to be written as a system of equations

Step-by-step explanation:

We can express an equation in one variable as follows;

f (x) = g (x)

The properties of equality of products allows us to write an equation in one variable into a system of equations as follows;

(x - 3) * (x + 2) = 0

The zero product property gives;

x - 3 = 0 or x + 2 = 0

Also we have;

Product of two negatives = positive

Therefore when (x - 2) ² = 25

x - 2 = ±5.
