Impara online a risolvere i problemi di passo dopo passo. 5x^2-7x+-5. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=5, b=-7 e c=-5. 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=5, b=-\frac{7}{5}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=5, b=-\frac{7}{5}x, c=-1, x^2+b=x^2-\frac{7}{5}x-1+\frac{49}{100}-\frac{49}{100}, f=\frac{49}{100} e g=-\frac{49}{100}. Applicare la formula: \frac{a}{b}+c=\frac{a+cb}{b}, dove a/b+c=\left(x- \frac{7}{10}\right)^2-1-\frac{49}{100}, a=-49, b=100, c=-1 e a/b=-\frac{49}{100}.
