Impara online a risolvere i problemi di completare il quadrato passo dopo passo. 31x^2-12x+36. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=31, b=-12 e c=36. 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=31, b=-\frac{12}{31}x e c=\frac{36}{31}. 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=31, b=-\frac{12}{31}x, c=\frac{36}{31}, x^2+b=x^2-\frac{12}{31}x+\frac{36}{31}+\frac{36}{961}-\frac{36}{961}, f=\frac{36}{961} e g=-\frac{36}{961}. Applicare la formula: \frac{a}{b}c=\frac{ca}{b}, dove a=6, b=31, c=-1, a/b=\frac{6}{31} e ca/b=- \frac{6}{31}.
