The polynomial equation x5-16x2=4x4-64 has complex roots + or - 2i what are the other roots? use a graphing calculator and a sys

Kindly proofread the question!!!

The leading term is x^6, not x5.

Answer: The additional roots are -2, +2, each with multiplicity 2.

Step-by-step explanation:

x^6 - 16x^2 = 4x^4 - 64

x^6 - 4x^4 - 16x^2 + 64 = 0

(x+2i)(x-2i) = (x^2+4) is a factor.

(x-2)(x+2)(x-2)(x+2)(x^2+4) = 0

Polynomial long division by x^2+4

x^6 - 4x^4 - 16x^2 + 64 = 0

First term of quotient is x^4

Subtract x^6+4x^4

Remainder is -8x^4 -16x^2+64

Second quotient term is -8x^2

Subtract -8x^4-32x^2

Remainder is 16x^2+64

Third quotient term is 16

Subtract 16x^2+64

Remainder is zero

Quotient is x^4 - 8x^2 + 16

(x^2-4)^2 = x^4 + 2(1)(-4)x^2 + 16

(x-2)(x+2)(x-2)(x+2)(x^2+4) = 0

Answer:

f(x) = (x + 10)(x + 4)(x - 1)

Step-by-step explanation:

Given the zeros of a polynomial, say x = a and x = b, then

the factors are (x - a) and (x - b)

The polynomial is then the product of the factors

f(x) = (x - a)(x - b)

Here the zeros are x = - 10, x = - 4 and x = 1, thus the factors are

(x - (- 10)), (x - (- 4)) and (x - 1), that is

(x + 10), (x + 4) and (x - 1)

f(x) = (x + 10)(x + 4)(x - 1)

Answer:

$6\pi$

Step-by-step explanation:

The area of the circumference of a circle is:

$C=2\pi r$

We know that r is 8, so we can plug that into the formula.

However, there's a problem. We only want 3pi/4 of the circumference, not the entire circle's circumference. Therefore, we have to divide by part/whole. In this case, the part is 3pi/4, and the whole is 2pi (the entire circle is 2pi radians).

$C = (\frac{3\pi/4}{2\pi})*(2\pi *8)\\C = (\frac{3}{8})(16\pi)\\C = \frac{48\pi }{8} \\C = 6\pi$
