Question

find an equation for a polynomial function p with zeros 2, -4, and 4/7

Answer 1

This time we can work backwards

We know the zeros are 2 , -4 an 4/7

so we just write

(x - 2)(x + 4)(x - 4/7)

And then we multiply it out...can you do that?

Answer 2

hmmm, ill try

Answer 3

Not quite I'd do it 2 terms at a time to make it easier



do that one :)
