Answer:

All I know

Step-by-step explanation:All I know is that you have to distribute the top so 5{2k - 3} so that would be 10k-15 and then -3{k+4} would be -3k -12 hopefully this helps you out a littble bit so the top completely is 7k-27

Answer:

  41/4 = 10.25

Step-by-step explanation:

Put -2 where k is and do the arithmetic.

\dfrac{5(2k-3)-3(k+4)}{3k+2}=\dfrac{5(2(-2)-3)-3(-2+4)}{3(-2)+2}\\\\=\dfrac{5(-4-3)-3(2)}{-6+2}=\dfrac{5(-7)-6}{-4}=\dfrac{-35-6}{-4}\\\\=\dfrac{41}{4}=10.25

According to the Fundamental Theorem of Algebra, which polynomial function has exactly 8 roots?
HACTEHA [7]

Answer:

Option (1)

Step-by-step explanation:

Fundamental theorem of Algebra states degree of the polynomial defines the number of roots of the polynomial.

8 roots means degree of the polynomial = 8

Option (1)

f(x) = (3x² - 4x - 5)(2x⁶- 5)

When we multiply (3x²) and (2x⁶),

(3x²)(2x⁶) = 6x⁸

Therefore, degree of the polynomial = 8

And number of roots = 8

Option (2)

f(x) = (3x⁴ + 2x)⁴

By solving the expression,

Leading term of the polynomial = (3x⁴)⁴

                                                     = 81x¹⁶

Therefore, degree of the polynomial = 16

And number of roots = 16

Option (3)

f(x) = (4x² - 7)³

Leading term of the polynomial = (4x²)³

                                                    = 64x⁶

Degree of the polynomial = 6

Number of roots = 6

Option (4)

f(x) = (6x⁸ - 4x⁵ - 1)(3x² - 4)

By simplifying the expression,

Leading term of the polynomial = (6x⁸)(3x²)

                                                     = 18x¹⁰

Degree of the polynomial = 10

Therefore, number of roots = 10
