Question

Use the function f(x) = 2x^4 - x^3 - 61x^2 +114x+72

a. Determine if x-4 and x+2 are factors of f(x). Justify your reasoning.

b. If you use division to completely factor a function, does it matter which factor you divide out first?

c. Given that -6 is a zero of the function and your results from part (a), write f(x) in factored form.

Explain how you used the factor theorem in your factoring

Answer 1

a.) can (x-4) and (x+2) divide into the original function?

b.) Well for this one you have to use division to find out. if the factors from part a. both work see if you can use either one of them first does it matter which one you use first?

c.)what is a zero?

Answer 2

You can use synthetic division

Answer 3

totes now actually do it and see what happens

Answer 4

would -4 be changed to positive 4 in order to divide?

Answer 5

nvm

Answer 6

that nvm.... its totally the sign of you learning and figuring it out on your own. knowing the answers doesnt help you know how to do it

Answer 7

x-4 is a factor.x-2 isnt

Answer 8

x+2?

Answer 9

yes, sorry. typo
