Impara online a risolvere i problemi di passo dopo passo. Solve the quadratic equation -8x^2+2x+-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=2 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}{4}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}{4}x, c=\frac{1}{8}, x^2+b=x^2-\frac{1}{4}x+\frac{1}{8}+\frac{1}{64}-\frac{1}{64}, f=\frac{1}{64} e g=-\frac{1}{64}. Applicare la formula: \frac{a}{b}c=\frac{ca}{b}, dove a=1, b=8, c=-1, a/b=\frac{1}{8} e ca/b=- \frac{1}{8}.
