Rewrite system as a single equation in n, by assuming that n3 = 0 and subtracting the remaining equations to get an equation for n′ = (n2 − n1)′.

n′ =(W+G)n

where W= \begin{bmatrix} -Wp&0&Wp\\ 0& 0& 0\\ Wp& 0 & -Wp \end{bmatrix} and G=\begin{bmatrix} 0 &r21 &r31 \\ 0&-r21&r32 \\ 0&0 &-r32-r31 \end{bmatrix}

because its not ur topic and its not for is for homework not that.

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!
