Ответ:
This means the two factors of the given polynomial are x - (5+3i) and x - (5 - 3i). The product of the factors must result in the original expression. So, we can write:
x² - (answer) + 34 = (x - 5 -3i)(x - 5 + 3i) (Equation 1)
Simplifying the right hand side:
Thus, we can write the Equation 1 as:
x² - (answer) + 34 = x² - 10x + 34
Comparing the two sides, we can conclude that the answer to this question is 10x.

Type the correct answer in the box. Use numerals instead of words.
Find the area of this shape.
The area of the shape is
35
square centimeters.
Step-by-step explanation:
Ответ:
part a)![x=3, y=-2](/tex.php?f=x=3, y=-2)
part b) verification in the procedure
part c) the graph in the attached figure
step-by-step explanation:
we have
part a) use substitution to find the solution to the systems of equations
in the equation a isolate the variable x
substitute equation c in equation b
find the value of x
the solution is equal to
part b) algebraically verify your answer to part a
we have that
the solution is![x=3, y=-2](/tex.php?f=x=3, y=-2)
verify in the equation a and in the equation b
equation a
substitute the value of x and the value of y in the equation and then compare
)=5[/tex]
equation b
substitute the value of x and the value of y in the equation and then compare
therefore
the point
satisfy both equations
hence
the point
is the solution of the system of equations
part c) graphically verify your answer to part a
we know that
the intersection point both graphs is the solution of the system of equations
using a graphing tool
see the attached figure
the intersection point is equal to![(3,-2)](/tex.php?f=(3,-2))
therefore
the point
is the solution of the system of equations
