Impara online a risolvere i problemi di passo dopo passo. 5x^2+8x+5. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=5, b=8 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=5, b=\frac{8}{5}x e c=1. 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=5, b=\frac{8}{5}x, c=1, x^2+b=x^2+\frac{8}{5}x+1+\frac{16}{25}-\frac{16}{25}, f=\frac{16}{25} e g=-\frac{16}{25}. Applicare la formula: \frac{a}{b}+c=\frac{a+cb}{b}, dove a/b+c=\left(x+\frac{4}{5}\right)^2+1-\frac{16}{25}, a=-16, b=25, c=1 e a/b=-\frac{16}{25}.
