Question

Find the zeros of the polynomial function.

f(x) = x^2 – 4x – 60

A.
–6, 10

B.
–10, 6

C.
–14, 5

D.
–5, 14

Answer 1

So first you need to be able to break it down. Do you know how to do that much?

Answer 2

It's fine if you don't. I can explain. :)

Answer 3

x^2-4x-60 is factorable to (x-10) (x+6)
so do you know what to do next? @mooshiex

Answer 4

I don't know how :/

Answer 5

not really @Yttrium

Answer 6

you can try using the quadratic equation:

\[x1x2 = \frac{ -b \pm \sqrt{b ^{2} - 4ac} }{ 2a }\]

where a = 1, b = -4 and c=-60

just put the numbers in the formula and you will get two solutions
