Answer:
x=0, -3/4
Step-by-step explanation:
We can solve by factoring. We will factor by GCF the greatest common factor. and
share several factors in common:
- they both share an x
- they both share 2
I pull out 2x and I get . I now set each factor equal to 0 and solve for x.
2x=0
x=0
4x+3=0
4x=-3
x=-3/4

Step-by-step explanation:
<u>Complex Numbers</u>
They are expressed as the sum of a real part and an imaginary part:
Complex numbers can also be expressed in polar form:
Where r is the modulus of the complex number and θ is the argument.
The argument can be calculated by:
The angle θ must be calculated in the appropriate quadrant depending on the signs of the real and imaginary parts.
The complex number is given as:
Here: a=-3, b=-9
Since both components are negative, the argument lies in the third quadrant (180° < θ < 270°).
The calculator gives the answer 71.6°, we need to adjust the angle to the third quadrant by adding 180°, thus
