Impara online a risolvere i problemi di completare il quadrato passo dopo passo. 2x^2-11x+-124. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=2, b=-11 e c=-124. 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=2, b=-\frac{11}{2}x e c=-62. 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=2, b=-\frac{11}{2}x, c=-62, x^2+b=x^2-\frac{11}{2}x-62+\frac{121}{16}-\frac{121}{16}, f=\frac{121}{16} e g=-\frac{121}{16}. Applicare la formula: \frac{a}{b}+c=\frac{a+cb}{b}, dove a/b+c=\left(x- \frac{11}{4}\right)^2-62-\frac{121}{16}, a=-121, b=16, c=-62 e a/b=-\frac{121}{16}.
