ok so i was presented with the equation x^2-7x+12=0 and i cant decide what the answer should be. if i factor the equation i come up with 3 and 4. but when i plug those back into the original equation it doesnt work. so does that mean that there is no answer or does it mean i'm doing something wrong?(adsbygoogle = window.adsbygoogle || []).push({});
