Question

What are the zeros of f(x) = x^2 - 5x -24?

Answer 1

Split the middle term! :)

Answer 2

Getting me?

Answer 3

not quite, do you mean split like x^2 + 1x +1 = (x+1)^2

Answer 4

\[x^2-5x-24=(x+3)(x-8)\] right?

Answer 5

EXACTLY! :D

Answer 6

so then the zeroes are 3 and -8, right?

Answer 7

Not quite :D
If
(x+3)(x-8) = 0
then
(x+3) = 0/(x-8) = 0
So x = -3
And same for (x_8)!! :D
Understood? :)

Answer 8

yes, thanks!

Answer 9
