Answer:
The fundamental theorem of algebra guarantees that a polynomial equation has the same number of complex roots as its degree.
Step-by-step explanation:
The fundamental theorem of algebra guarantees that a polynomial equation has the same number of complex roots as its degree.
We have to find the roots of this given equation.
If a quadratic equation is of the form 
Its roots are
and 
Here the given equation is
= 0
a = 2
b = -4
c = -1
If the roots are
, then
= 
= 
= 
= 
= 
= 
These are the two roots of the equation.
Answer:
The same number as in the multiplier
Step-by-step explanation:
The number of decimal places in the product is the sum of the decimal places in the factors.
A natural number is an integer. It has no decimal places.
So, the product has the product has the same number of decimal places as the multiplier.
For example, 2 × 3.45 = 6.90
The number 3.45 has two decimal places, so the product has two decimal places.
Answer:
C
Step-by-step explanation:
ok so sam started with 0 and got -9 then he got 12 then the next known number is -8 so those three numbers together are -5 and the end result was -1 so -1 minus -5 is -4 therefore the anser is C
2 tens = 20
13 ones = 13
20 + 13 = 33
33 is your answer
hope this helps
