Impara online a risolvere i problemi di passo dopo passo. 11x^2+22x+-15. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=11, b=22 e c=-15. 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=11, b=2x e c=-\frac{15}{11}. 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=11, b=2x, c=-\frac{15}{11}, x^2+b=x^2+2x-\frac{15}{11}+1-1, f=1 e g=-1. Applicare la formula: \frac{a}{b}+c=\frac{a+cb}{b}, dove a/b+c=\left(x+1\right)^2-\frac{15}{11}-1, a=-15, b=11, c=-1 e a/b=-\frac{15}{11}.
