Impara online a risolvere i problemi di passo dopo passo. Solve the quadratic equation -8x^2-x+-1=0. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=-8, b=-1 e c=-1. 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=-8, b=\frac{1}{8}x e c=\frac{1}{8}. 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=-8, b=\frac{1}{8}x, c=\frac{1}{8}, x^2+b=x^2+\frac{1}{8}x+\frac{1}{8}+\frac{1}{256}-\frac{1}{256}, f=\frac{1}{256} e g=-\frac{1}{256}. Applicare la formula: ax=b\to \frac{ax}{a}=\frac{b}{a}, dove a=-8, b=0 e x=\left(x+\frac{1}{16}\right)^2+\frac{1}{8}-\frac{1}{256}.
