Impara online a risolvere i problemi di passo dopo passo. Solve the quadratic equation -8x^2+3x+-7=0. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=-8, b=3 e c=-7. 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{3}{8}x e c=\frac{7}{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{3}{8}x, c=\frac{7}{8}, x^2+b=x^2-\frac{3}{8}x+\frac{7}{8}+\frac{9}{256}-\frac{9}{256}, f=\frac{9}{256} e g=-\frac{9}{256}. Applicare la formula: \frac{a}{b}c=\frac{ca}{b}, dove a=3, b=16, c=-1, a/b=\frac{3}{16} e ca/b=- \frac{3}{16}.
