Answer:
The Obvious
Euler graph all connects almost like a circle
A tree graph looks like it branches off each other with no line connect in a circle like form
Got your answer.
I drew it out on a digital drawing software I have.
Answer:
- there are 4 complex solutions
- 3 real zeros and 2 complex zeros
Step-by-step explanation:
1. Descarte's rule of signs tells you there are 0 positive real roots and 0 or 2 negative real roots. (for positive x, signs are ++++ so have no changes; for negative x, signs are ++-+, so have 2 changes.) A graph shows no real roots.
2. There are 3 sign changes in the given polynomial, so 3 or 1 positive real roots. When the sign of x is changed, there are 2 sign changes, so 0 or 2 negative real roots. A graph shows 2 negative and one positive real root (for a total of 3), so the remaining 2 roots are complex.
Step-by-step explanation:
We multiply it to find the product
positive times positive = positive
positive times negative = negative
negative times positive = negative
negative times negative = positive

Negative and negative is positive , so product is positive

Negative and positive is negative , so product is negative

positive and negative is negative , so product is negative

positive and positive is positive , so product is positive
