Impara online a risolvere i problemi di passo dopo passo. Solve the inequality -10x^2+7x+25>=0. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=-10, b=7 e c=25. 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=-10, b=-\frac{7}{10}x e c=-\frac{5}{2}. 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=-10, b=-\frac{7}{10}x, c=-\frac{5}{2}, x^2+b=x^2-\frac{7}{10}x-\frac{5}{2}+\frac{49}{400}-\frac{49}{400}, f=\frac{49}{400} e g=-\frac{49}{400}. Applicare la formula: \frac{a}{b}c=\frac{ca}{b}, dove a=7, b=20, c=-1, a/b=\frac{7}{20} e ca/b=- \frac{7}{20}.
