Question

describe how you would find all possible rational zeros of the polynomial function f(x)=4x^3-5x^2+9x-6

Answer 1

you could use division....

or you could draw it on the graph.. plotting x vaues versus y values and see where the croos the y axis

Answer 2

1st use guess and check

f(2) = 0

so (x-2) is a factor

then polynomial division

Answer 3

Thank you, but what are the rational zeros do you know?

Answer 4

the 1st is at x = 2

do the division to find the factors and solve

Answer 5

the function if f(x) = (x-2)(4x^2 + 3x +15) + 24
