Use the fundamental theorem of algebra to determine the number of roots for each polynomial function shown. f (x) = 2x3 + x2 - 7x + 1 has roots. f (x) = -3x + 5x2 + 8 has roots. f (x) = (x2 + 6)2 has roots.

1.) f (x) = 2x3 + x2 - 7x + 1 has 3 roots.

2.) f (x) = -3x + 5x2 + 8 has 2  roots.

3.) f (x) = (x2 + 6)2 has 4 roots.

Step-by-step explanation:

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.
