Impara online a risolvere i problemi di passo dopo passo. 25x^2+60x+9. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=25, b=60 e c=9. 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=25, b=\frac{12}{5}x e c=\frac{9}{25}. 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=25, b=\frac{12}{5}x, c=\frac{9}{25}, x^2+b=x^2+\frac{12}{5}x+\frac{9}{25}+\frac{36}{25}-\frac{36}{25}, f=\frac{36}{25} e g=-\frac{36}{25}. Applicare la formula: \frac{a}{b}+\frac{c}{b}=\frac{a+c}{b}, dove a=9, b=25 e c=-36.
