Impara online a risolvere i problemi di passo dopo passo. 3u^2-11u+-5. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=3, b=-11, c=-5 e x=u. 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{11}{3}u, c=-\frac{5}{3} e x=u. 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{11}{3}u, c=-\frac{5}{3}, x^2+b=u^2-\frac{11}{3}u-\frac{5}{3}+\frac{121}{36}-\frac{121}{36}, f=\frac{121}{36}, g=-\frac{121}{36}, x=u e x^2=u^2. Applicare la formula: \frac{a}{b}c=\frac{ca}{b}, dove a=11, b=6, c=-1, a/b=\frac{11}{6} e ca/b=- \frac{11}{6}.
