The count the number of times the sign changes
that is how many positive roots there are
if you get a number that is ≥2, then count down by 2's ending at 0
sub -x for x and evaluate
count change in sign again
that is how many negative roots there are
if you get a number that is ≥2, then count down by 2's ending at 0
so
-2x^3+3x^2-5x-2=0
-,+,-,-
1 2
2 or 0 positive roots
x to -x
2x^3+3x^2+5x-2=0
+,+,+,-
1
1 negative root
2 or 0 positive roots and 1 negative root
D is answer
<u>Answer:</u>
Binomial is a factor of the polynomial.
<u>Step-by-step explanation:</u>
You can divide a polynomial with a binomial by using synthetic division in the form x - c. We can use this to find several things: the quotient and the remainder you get when you divide the polynomial function by x - c.
For a binomial which divides a polynomial completely, giving a remainder of zero and some quotient then it means that the binomial is a factor of that polynomial.
Answer:
You are correct
Step-by-step explanation:
That is the correct answer. It cannot be a reflection because the orientation is the same.
Answer:
x= -4
Step-by-step explanation:
Answer:
36
Step-by-step explanation:
-7-2=-9
due to the absolute value symbol placed before and after "m - n"; your answer will be a positive; -9 = 9(+)--> times 4= 36
4|m-n| = 36
