Answer:
they just go straight what does it mean?
I remember dis, yey
so if a polynomial has roots

,

,

, it can be factored into

where a,b,c,d are constants
also, if a polynomial has rational coefients and a+bi is a root, then a-bi must also be a root
so our roots we need are
4,16, 1+9i and 1-9i
so assuming multiplity 1 (that means we have something like [/tex]f(x)=a(x-r_1)^1(x-r_2)^1(x-r_3)^1[/tex])
we get that your function is

which simplifies to

which expands to
Answer:

Answer:
x = 704/39 ( <----Fraction)
Step-by-step explanation:
28 squared minus 39x minus 80 equals 0
784-39x-80=0 evaluate the power
704-39x=0 Subtract the numbers
-39x=-704 move the constant to the right hand side and change it's sign
Divide on both side to get x = 704/39
