Impara online a risolvere i problemi di passo dopo passo. 3x^2-7x+-3. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=3, b=-7 e c=-3. Applicare la formula: a\left(x^2+b+c\right)=a\left(x^2+b+c+\left(\frac{coef\left(b\right)}{2}\right)^2-\left(\frac{coef\left(b\right)}{2}\right)^2\right), dove a=3, b=-\frac{7}{3}x e c=-1. Applicare la formula: a\left(x^2+b+c+f+g\right)=a\left(\left(x+\sqrt{f}sign\left(b\right)\right)^2+c+g\right), dove a=3, b=-\frac{7}{3}x, c=-1, x^2+b=x^2-\frac{7}{3}x-1+\frac{49}{36}-\frac{49}{36}, f=\frac{49}{36} e g=-\frac{49}{36}. Applicare la formula: \frac{a}{b}+c=\frac{a+cb}{b}, dove a/b+c=\left(x- \frac{7}{6}\right)^2-1-\frac{49}{36}, a=-49, b=36, c=-1 e a/b=-\frac{49}{36}.
