Write a polynomial function of minimum degree with real coefficients whose zeros include those listed. Write the polynomial in s

Jobisdone [24]

Answer:

$f(x)=x^4-9x^2-50x-150$

Step-by-step explanation:

Let f(x) be the polynomial function of minimum degree with real coefficients whose zeros are 5, -3, and -1 + 3i be f(x).

By the complex conjugate property of polynomials, -1-3i is also a root of this polynomial.

Therefore the polynomial in factored form is $f(x)=(x-5)(x+3)(x-(-1+3i))(x-(-1+3i))$

We expand to get: $f(x)=(x^2-2x-15)(x^2+2x+10)$

We expand further to get:\

$f(x)=x^4-9x^2-50x-150$

A square is shown below. Which expression can be used to find the area, in square units, of the shaded triangle in the square?

ELEN [110]

Answer:

Area = $\frac{1}{2} (6)(6)$

Step-by-step explanation:

Area of Triangle = $\frac{1}{2} (Base)(Height)$

Where Base = 6 , Height = 6

Area = $\frac{1}{2} (6)(6)$

Area = 3 * 6

Area = 18 units^2

Which expression represents the polynomial −2x^2−4x^4+8x+x^5−2x^3 rewritten in descending order?

tigry1 [53]

The polynomial $-2x^2-4x^4+8x+x^5-2x^3$ arranged in descending order is $x^5-4x^4-2x^3-2x^2+8x$

Step-by-step explanation:

We need to rewrite the polynomial $-2x^2-4x^4+8x+x^5-2x^3$ in descending order.

For writing the polynomial in descending order we arrange the exponents of variables from largest exponent to the smallest exponent.

The given polynomial is:

$-2x^2-4x^4+8x+x^5-2x^3$

The descending order of the polynomial is:

$x^5-4x^4-2x^3-2x^2+8x$

So, the polynomial $-2x^2-4x^4+8x+x^5-2x^3$ arranged in descending order is $x^5-4x^4-2x^3-2x^2+8x$
