Estou estudando função quadrática e, me confundo bastante na resolução do gráfico, a conta de bháskara eu faço com facilidade, mas quando não existem números suficientes para atribuir a "b" e "c", por exemplo, b²-4ac, eu não sei realmente aplicar o calculo -b\2a, e para piorar, quando o professor passou esse matéria em aula on-line, a internet tinha caído no meu bairro. Alguém pode me explicar?
