Impara online a risolvere i problemi di passo dopo passo. 9x^2-3x+2. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=9, b=-3 e c=2. 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=9, b=-\frac{1}{3}x e c=\frac{2}{9}. 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=9, b=-\frac{1}{3}x, c=\frac{2}{9}, x^2+b=x^2-\frac{1}{3}x+\frac{2}{9}+\frac{1}{36}-\frac{1}{36}, f=\frac{1}{36} e g=-\frac{1}{36}. Applicare la formula: \frac{a}{b}c=\frac{ca}{b}, dove a=1, b=6, c=-1, a/b=\frac{1}{6} e ca/b=- \frac{1}{6}.
