Impara online a risolvere i problemi di completare il quadrato passo dopo passo. 3.1-8.0f16f^2. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=16, b=-8, c=\frac{31}{10} e x=f. 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=16, b=-0.5f, c=0.19375 e x=f. 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=16, b=-0.5f, c=0.19375, x^2+b=f^2-0.5f+0.19375+0.0625-0.0625, f=\frac{1}{16}, g=-\frac{1}{16}, x=f e x^2=f^2. Applicare la formula: a+b=a+b, dove a=0.19375, b=-\frac{1}{16} e a+b=\left(f-0.25\right)^2+0.19375-0.0625.
