Answer:

6 roots

Step-by-step explanation:

we know that

The number of roots is determined by the degree of the polynomial. They may be real or complex.

In this problem we have

$f(x)=3x^{6}+2x^5+x^4-2x^3$

The degree refers to the highest exponent of the polynomial

Since this is a 6th degree polynomial, it will have 6 roots

nadya68 [22]

Answer:

Step-by-step explanation:

The number that take algebra i includes those who take both subjects, as does the number taking algebra ii. Then the number taking algebra i alone is ...

18 -10 = 8 . . . . . take only algebra i

So the number taking any kind of algebra is ...

20 + 8 = 28

and the number not taking either subject is ...

60 -28 = 32 . . . not taking either subject
