Question

What is the factored form of 3xsquared -9x+12

Answer 1

x_1,_2=(9+/- sqrt(81-144))/6=(9+/- sqrt(-63))/6=(9+/- i3sqrt(7))/6=
=3(3+/- isqrt(7))/6=(3+/- isqrt(7))/2

- those are solutions

Answer 2

3x^2 - 9x + 12
=3(x^2-3x+4)
=3x(x-3) + 12

it can't be completely factored though.
Please make sure the question is posted correctly.

Answer 3

unless it's acceptable to have complex numbers in the solution.
