Why can't I get two solutions from quadratics?
I teach science and it would be useful to see both (or all) numerical answers with one click in CAS. Sometimes I get them. Sometimes I don't. Sometimes GG adds x=1 on the line and shows just one answer. Sometimes it doesn't. I've been trying to use the command NSolve different ways and the buttons too. I just can't find a logic here.
Could anyone help me? What should I do to see both numerical answers for a quadratic?
