<span>x² – 12 = –4x
</span>x² +4x– 12=0
(x+6)(x-2)=0
so 
x+6=0     or   x-2=0
x=-6                 x=2

(-6,2)

X^2+4x-12=0

x^2-2x+6x-12=0

x(x-2)+6(x-2)=0

(x-2)(x+6)=0

x=-6 and 2

Patrick is an electrical engineer who is testing the voltage of a circuit given a certain current and resistance. He uses the fo
morpeh [17]

Based on the given current and the given resistance, the voltage of the current is 14 + j8

<h3>How to determine the voltage of the current?</h3>

From the question, we have the following parameters

current of 4+j2 amps and a resistance of 2-j3 ohms.

This can be rewritten as:

Current (I) = 4+j2 amps

Resistance (R) = 2-j3 ohms.

The formula to calculate voltage is given as

Voltage=(current) × (resistance)

Rewrite as:

V = I * R

Substitute the known values in the above equation

V = (4 + j2) * (2 - j3)

Expand the brackets

V = 8 - j4 + j12 + 6

Collect the like ters

V = 8 + 6 - j4 + j12

Evaluate the like term

V = 14 + j8

Based on the given current and the given resistance, the voltage of the current is 14 + j8
