Impara online a risolvere i problemi di disuguaglianze passo dopo passo. 3x^2+25x+63. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=3, b=25 e c=63. 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=3, b=\frac{25}{3}x e c=21. 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=3, b=\frac{25}{3}x, c=21, x^2+b=x^2+\frac{25}{3}x+21+\frac{625}{36}-\frac{625}{36}, f=\frac{625}{36} e g=-\frac{625}{36}. Applicare la formula: \frac{a}{b}+c=\frac{a+cb}{b}, dove a/b+c=\left(x+\frac{25}{6}\right)^2+21-\frac{625}{36}, a=-625, b=36, c=21 e a/b=-\frac{625}{36}.
