Why won't ti89 factor this expression?

Question

My ti89 factors all other expressions, yet will not return an answer for the following equation:

2(3x^2+26x+60)

Any suggestions?

Answer 1

Favourite answer

is it a typo?

3(2x^2+26x+60) is factorable, but I don't see the factors for the one you wrote, check for transcription error!?

Answer 2

We can forget the number 2 in the start. It don't matter.

The roots are 26/6+-sqrt(26^2 /6^2 - 60)

The answer is imaginary

Answer 3

I have no clue why, but why don't you just multiply the Quadratic by two? And then use your calculator to factor it.
