Answer:</h2>
The simplified form of the given polynomial equation is:
<h2>
Step-by-step explanation:</h2>
We are asked to simplify the given polynomial expression in terms of the variable x.
The algebraic expression is given as:
On taking out the terms from both the brackets the sign of the terms of the second bracket gets interchanged as there is a negative sign preceding it.
Hence, we get the expression as:
Now on combining the like terms we get:
The current it conduct when it is plugged into a wall outlet that provides 120 V is 10.4A
<h3>Ohms law</h3>
The current passing through a conductor is proportional to the potential difference. Mathematically;
V = IR
where
V is the voltage = 120V
R is the resistance = 11.5 ohms
Required
Current I
Substitute
I = V/R
I = 120/11.5
I = 10.4A
Hence the current it conduct when it is plugged into a wall outlet that provides 120 V is 10.4A

When you multiply anything by zero, you will get zero
Therefore you know that:
x = 0 and 2x - 5 = 0
2x - 5 = 0, solve for x
2x = 5, x = 5/2
Solution: x = 5/2, x = 0
The answer should be
