f(x)=x^2-2x-3

Parth (parthkohli):

\(\Large \color{purple}{\rightarrow f(x) = x^2 - 3x + x - 3 }\) \(\Large \color{purple}{\rightarrow f(x) = x(x - 3) + 1(x - 3) }\) \(\Large \color{purple}{\rightarrow f(x) = (x + 1)(x - 3) }\)

OpenStudy (anonymous):

answers are: A. (-1,-4). B. (-1,-2). C.(1,-4). D.(1,-2).

OpenStudy (anonymous):

so what's the question then?

OpenStudy (anonymous):

@ParthKohli factored the expression for you... it should be easy finding the zeros.

OpenStudy (anonymous):

f(x)=\[x^2-2x-3\]

OpenStudy (anonymous):

1 and -3?

OpenStudy (anonymous):

thats not one of my answers!

OpenStudy (diyadiya):

What is your question ? to factor ?

OpenStudy (anonymous):

all you have is an equation up there, what's the question?

OpenStudy (anonymous):

she's gone!

Parth (parthkohli):

-1 and 3 should be the answers.

OpenStudy (diyadiya):

Oh thats right !!

OpenStudy (diyadiya):

But thats not one of the choices

OpenStudy (anonymous):

still, that's not one of the choices... :)

OpenStudy (anonymous):

i know

OpenStudy (anonymous):

the question is determine the vertex of the parabola formed by f(x)=x^2-2x-3.

Parth (parthkohli):

Check for some mistake in the question or the choices again please.

OpenStudy (anonymous):

there is no mistake.
