Over the reals, is (-1)x²+(9)x+(-3)=0 a quadratic equation in one variable? Answer Yes or No.
G001 — Over the reals, is (-1)x²+(9)x+(-3)=0 a quadratic equation in one variable? Answer Yes or No.Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.

Conditions: none
Only a!=0 is quadratic.Here a0 is a legal eligibilityNo and may leave a linear,constant or zero expression;do not apply the quadratic formula.
