1) (-7+20)(-10-3i)
2) (-2-5i)/(3+4i)
I don't think I did these two questions right does anyone know how?
2) (-2-5i)/(3+4i)

HawKMX2004 said:1) (-7+20)(-10-3i)
Step 1.) FOIL the Problem
Step 2.) Simplify from there (Do addition Subtraction etc.)
2) (-2-5i)/(3+4i)
I forgot how to do division with imaginary numbers I'll try to look it back up and give you some help
vladimir69 said:yes you are right again
(-2-5i)/(3+4i) does equal (-26-7i)/25
To simplify conjugate expressions means to combine or manipulate mathematical expressions that involve conjugates, which are pairs of complex numbers with the same real part but opposite imaginary parts.
Simplifying conjugate expressions can make mathematical calculations easier and more efficient. It can also help in identifying patterns and relationships among complex numbers.
The basic rules for simplifying conjugate expressions include distributing, combining like terms, and using the conjugate property (i.e. multiplying a conjugate pair results in a difference of squares).
Yes, conjugate expressions can be simplified to a single number by using the conjugate property and performing basic mathematical operations, such as addition, subtraction, multiplication, and division.
Simplifying conjugate expressions can be applied in various fields such as engineering, physics, and economics, where complex numbers are commonly used in calculations. It can also be used in solving problems involving waves, electric circuits, and signal processing.
