How can you quickly determine the number of roots a polynomial will have by looking at the eqation?

1 answer:

3 0

Easy way is to look at the term with the highest exponent. The exponent determines the number of roots. Some might be double roots. THough not all of then will be real. The imaganry ones come in pairs
Examples:
x^4 - 4 roots
x^7 - 7 roots
x^3 - 3 roots

If vector v has an initial point at P1 and a terminal point at P2, write v as multiples of the basis vectors That is, write v in

pantera1 [17]

Answer:

v=9i+3j

Step-by-step explanation:

The given vector, v has initial point at P1 = (−5, −2) and terminal point at P2 = (4, 1).

The vector v is found by subtraction the initial point from the terminal point.

v=<4,1>-<-5,-2>

v=<4--5,1--2>

v=<9,3>

We write v as multiples of the basis vectors to obtain:

v=9i+3j
