Help pls!!! If a1 = 6 and an 2an-1 then find the value of a4.

1 answer:

3 0

24? I am not entirely sure but I think a4=24

Reason: if a1 equals 6 then I would like to think you would multiply 6 by 4 to get the value of a4 (I haven’t done this type of math in a while)

Polynomial function in standard form with zeros 5,-4,1

Oksanka [162]

Answer:

$\boxed{\sf \ \ \ x^3-2x^2-19x+20 \ \ \ }$

Step-by-step explanation:

hello,

by definition we can write

$(x-5)(x+4)(x-1)$

as 5,-4,1 are the zeroes

now we have to write it in the standard form, let's do it

$(x-5)(x+4)(x-1)=(x^2+4x-5x-20)(x-1)\\=(x^2-x-20)(x-1)=x^3-x^2-20x-x^2+x+20\\=x^3-2x^2-19x+20$

hope this helps
