Impara online a risolvere i problemi di completare il quadrato passo dopo passo. 0.02x^2-4.0x+1000. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=\frac{1}{50}, b=-4 e c=1000. 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=\frac{1}{50}, b=-200x e c=50000. 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=\frac{1}{50}, b=-200x, c=50000, x^2+b=x^2-200x+50000+10000-10000, f=10000 e g=-10000. Applicare la formula: a+b=a+b, dove a=50000, b=-10000 e a+b=\left(x-100\right)^2+50000-10000.
