Impara online a risolvere i problemi di completare il quadrato passo dopo passo. 3z^2-11z+-6. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=3, b=-11, c=-6 e x=z. 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{11}{3}z, c=-2 e x=z. 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{11}{3}z, c=-2, x^2+b=z^2-\frac{11}{3}z-2+\frac{121}{36}-\frac{121}{36}, f=\frac{121}{36}, g=-\frac{121}{36}, x=z e x^2=z^2. Applicare la formula: \frac{a}{b}+c=\frac{a+cb}{b}, dove a/b+c=\left(z- \frac{11}{6}\right)^2-2-\frac{121}{36}, a=-121, b=36, c=-2 e a/b=-\frac{121}{36}.
