How many terms are in this equation <br> 8y-6y^2/7^3
vlada-n [284]

Answer:

2

Step-by-step explanation:

You count terms that are seperated by - and + signs. Any type of fraction is considered one term.

So you count 8y as one term and the rest is a whole fraction so you also count that as one term.

You add all the terms together and you have 2 terms in this equation.

Hope this helped :)

Write a polynomial function with the given zeros x=-1,-1,6
damaskus [11]

Hello from MrBillDoesMath!

Answer:

x^3 - 6 x^2 - x + 6


Discussion:

The polynomial is

(x-1) (x - (-1)) (x-6) =

(x-1)(x+1)(x-6) =                     => as (x-1)(x+1) = x^2 - 1

(x^2-1)(x-6) =    

x^2(x) - 6 x^2 - 1x + 6 =

x^3 - 6 x^2 - x + 6



Thank you,

MrB
