Impara online a risolvere i problemi di completare il quadrato passo dopo passo. 4400x^2+220x+-0.15. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=4400, b=220 e c=-\frac{3}{20}. 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=4400, b=0.05x e c=-3.409090909090909E-5. 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=4400, b=0.05x, c=-3.409090909090909E-5, x^2+b=x^2+0.05x-3.41\times 10^{-5}+6.25\times 10^{-4}-6.25\times 10^{-4}, f=\frac{1}{1599} e g=-\frac{1}{1599}. Applicare la formula: a+b=a+b, dove a=-3.409090909090909E-5, b=-\frac{1}{1599} e a+b=\left(x+0.025\right)^2-3.41\times 10^{-5}-6.25\times 10^{-4}.
