Determine the equation of the polynomial, p(x),in both factored and standard form.

melamori03 [73]

We can see that the graph touches $x=-1$ without crossing the x-axis (i.e. it is a double solution), and then there's another zero at $x=2$ (this time it's a crossing zero, so a single solution).

This leads, up to multiple, to the polynomial

$p(x)=a(x+1)^2(x-2)$

If we impose the passing through $(0,4)$ we have

$p(0)=4=a(1)(-2) \iff -2a=4 \iff a=-2$

So, the polynomial is

$p(x)=-2(x+1)^2(x-2)=-2 x^3 + 6 x + 4$

Finally, to solve $p(x)$ , simply look at the graph, searching for the points, where the graph is below the x-axis. You can see that this happens only if $x>2$ , so that's the solution to your question.

Write (1/3i)-(-6+2/3i) as a complex number in standard form

Eddi Din [679]

Answer:

$6+\frac{i}{3}$

Step-by-step explanation:

$\frac{1}{3\imath}-(-6+\frac{2}{3\imath})$

$\frac{1}{3\imath}+6-\frac{2}{3\imath}$

taking like terms together

$\frac{1}{3\imath}-\frac{2}{3\imath}+6$

taking LCM

$\frac{1-2}{3\imath}+6$

$\frac{-1}{3\imath}+6$

taking LCM

$\frac{-1+18\imath}{3\imath}$

splitting the term

$\frac{-1+18\imath}{3\imath}$

splitting the term

$-\frac{1}{3\imath}+\frac{18\imath}{3\imath}$

$-\frac{1\times3\imath}{3\imath \times \imath}+6$

$-\frac{i}{3\imath^2}+6$

we know that

$\imath^2=-1$

putting this value in above equation

$\frac{\imath}{3}+6$
