Determine the multiplicity of the roots of the function k(x) = x(x + 2)3(x + 4)2(x − 5)4. 0 has multiplicity −2 has multiplicity
wolverine [178]

Answer:

0 has multiplicity 1

-2 has multiplicity 3

-4 has multiplicity 2

5 has multiplicity 4

Step-by-step explanation:

The multiplicity of the root of a polynomial function, refers to the number of time the root repeats itself.

The given function is

k(x)=x(x+2)^3(x+4)^2(x-5)^4

To find the roots of this function, we equate the function to zero.

x(x+2)^3(x+4)^2(x-5)^4=0

We now use the zero product principle, to obtain;

x=0, with multiplicity 1

(x+2)^3=0

\Rightarrow x=-2, with multiplicity 3

(x+4)^2=0

\Rightarrow x=-4, with multiplicity 2

(x-5)^4=0

\Rightarrow x=5, with multiplicity 5.

How many solutions does this equation have? -2-5x= -(5x+2)
Leno4ka [110]

Answer:

Infinite solutions

Step-by-step explanation:

A linear equation is given to us and we need to tell the no. of solutions. The equation is ,

=> -2-5x = - ( 5x +2)

If we look at RHS , negative sign is present outside the brackets .On opening the brackets , we have ,

=> -(5x) -(+2)

=> -5x -2

=> -2 - 5x

This is similar to LHS and hence they will represent same line . Hence they will have infinitely many solutions .

<h3><u>They have infinitely many solutions .</u></h3>
