Impara online a risolvere i problemi di passo dopo passo. -16x^2+80x+1600. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=-16, b=80 e c=1600. 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=-5x e c=-100. 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=-5x, c=-100, x^2+b=x^2-5x-100+\frac{25}{4}-\frac{25}{4}, f=\frac{25}{4} e g=-\frac{25}{4}. Applicare la formula: \frac{a}{b}+c=\frac{a+cb}{b}, dove a/b+c=\left(x- \frac{5}{2}\right)^2-100-\frac{25}{4}, a=-25, b=4, c=-100 e a/b=-\frac{25}{4}.
