What are the zeros of the function? h(x)=x^3−2x^2−3x

maksim [4K]

To find the zeroes you make the function equal to zero and then solve.
$0=x^3-2x^2-3x$
Then factor out the x to get a quadratic inside the parentheses.
$0=x(x^2-2x-3)$
Factor the inside quadratic formula.
$x(x^2-2x-3)=x((x-3)(x+1))$
Lastly, use the zero product property to solve.
$x*(x-3)*(x+1)=0$
$x=0,x=3,x=-1$

Can someone please solve this?

Molodets [167]

Multiplicity of a root means, is there that many times.

$\bf \begin{cases}
x=3\implies &x-3=0\\
x=2\implies 
&\begin{cases}
x-2=0\\
x-2=0\\
x-2=0
\end{cases}
\end{cases}
\\\\\\
(x-3)(x-2)~~(x-2)(x-2)=\textit{original polynomial}
\\\\\\
(x^2-5x+6)~~(x^2-4x+4)=y
\\\\\\
x^4-4x^3+4x^2-5x^3+20x^2-20x+6x^2-24x+24=y
\\\\\\
1x^4-9x^3+30x^2-44x+24=y$

Please help! Thanks!: If a 95% confidence interval was being calculated using the following expression:

Roman55 [17]

The confidence interval can be calculated from the margin of error, and vice versa,

The margin of error of the confidence interval is 2.156

The confidence interval is given as:

$\mathbf{CI = 3.2 \pm 1.96 \cdot 1.1}$
