Impara online a risolvere i problemi di completare il quadrato passo dopo passo. 2t^2-13t+-14. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=2, b=-13, c=-14 e x=t. 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=2, b=-\frac{13}{2}t, c=-7 e x=t. 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=2, b=-\frac{13}{2}t, c=-7, x^2+b=t^2-\frac{13}{2}t-7+\frac{169}{16}-\frac{169}{16}, f=\frac{169}{16}, g=-\frac{169}{16}, x=t e x^2=t^2. Applicare la formula: \frac{a}{b}+c=\frac{a+cb}{b}, dove a/b+c=\left(t- \frac{13}{4}\right)^2-7-\frac{169}{16}, a=-169, b=16, c=-7 e a/b=-\frac{169}{16}.
