Impara online a risolvere i problemi di disuguaglianze passo dopo passo. 18x^2-13x+5. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=18, b=-13 e c=5. 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=18, b=-\frac{13}{18}x e c=\frac{5}{18}. 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=18, b=-\frac{13}{18}x, c=\frac{5}{18}, x^2+b=x^2-\frac{13}{18}x+\frac{5}{18}+\frac{169}{1296}-\frac{169}{1296}, f=\frac{169}{1296} e g=-\frac{169}{1296}. Applicare la formula: \frac{a}{b}c=\frac{ca}{b}, dove a=13, b=36, c=-1, a/b=\frac{13}{36} e ca/b=- \frac{13}{36}.
