Impara online a risolvere i problemi di passo dopo passo. Solve the inequality -8x^2-20x+48>=0. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=-8, b=-20 e c=48. 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{5}{2}x e c=-6. 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{5}{2}x, c=-6, x^2+b=x^2+\frac{5}{2}x-6+\frac{25}{16}-\frac{25}{16}, f=\frac{25}{16} e g=-\frac{25}{16}. Applicare la formula: \frac{a}{b}+c=\frac{a+cb}{b}, dove a/b+c=\left(x+\frac{5}{4}\right)^2-6-\frac{25}{16}, a=-25, b=16, c=-6 e a/b=-\frac{25}{16}.
