The polynomial of degree 3, P(x), has a root of. multiplicity 2 at x=1 and a roof of multiplicity 1 at x= -3. the y- intercept i
Stella [2.4K]

P(x) has degree 3, so it takes the general form

P(x)=ax^3+bx^2+cx+d

It has a root x=1 of multiplicity 2, which means (x-1)^2 divides P(x) exactly, and it has a root of x=-3 of multiplicity 1 so that x+3 also is a factor. So

P(x)=a(x-1)^2(x+3)

Expanding this gives

P(x)=a(x^3+x^2-5x+3)=ax^3+ax^2-5ax+3a

\implies\begin{cases}a=b\\-5a=c\\3a=d\end{cases}

The y-intercept occurs for x=0, for which we have

P(0)=d=2.1

Then

3a=d\implies a=0.7

a=b\implies b=0.7

-5a=c\implies c=-0.14

So we have

\boxed{P(x)=0.7x^3+0.7x^2-0.14x+2.1}
