Question

What are the zeros of the polynomial function: f(x) = (x - 4)(2x - 1)(x + 7)?

Answer 1

equate each factor to zero

x - 4 = 0
2x - 1= 0
x+7 = 0

from there solve for the three x's

Answer 2

uhmm need more help @tien.lam12 ?

Answer 3

thats it thanks

Answer 4

owkay :)

Answer 5

Set all the equation to 0...and then solve

Answer 6

So you have: x - 4 = 0, which becomes x = 4
2x - 1 = 0, which becomes 2x = 1, then x = 1/2
x + 7 = 0, so x = -7
Hope this helps.
