Question

Help please? Factor completely: −4x2 + 16x − 24

Answer 1

-4(x-2)^2 - 8

Answer 2

thanks (:

Answer 3

no problem ^^

Answer 4

that is an alternate form, but it is certainly not in factored form

Answer 5

it isn't?

Answer 6

\[−4x^2 + 16x − 24 \] all terms have a common factor of \(- 4\)
you can start with \[-4(x^2-4x+6)\]

Answer 7

and actually that is the best you can do, because the inside piece does not factor

Answer 8

\[y=-4(x-2)^2 - 8
\] is "vertex" from, not factored form

Answer 9

oh okay

Answer 10

thanks
