Question

how do you factor x^2-4x+24

Answer 1

Find the roots :-D

\[x^2 - 4x + 4 = -20\]
\[(x-2)^2 = -20 \]The above statement is false, so you cannot factor x^2-4x+24

Answer 2

If you must factor it, however, you may use complex numbers.

Answer 3

its not factorable, u can try using the quadratic formula

Answer 4

ok thanks

Answer 5

\[x - 2=i\sqrt{20}=2\sqrt{5}*i\]or\[x-2=-i\sqrt{20}=-2\sqrt{5}*i\]

Answer 6

It may therefor be factored into\[(x - (2-2\sqrt{5}*i))(x-(2+2\sqrt{5}*i))\]
