Impara online a risolvere i problemi di completare il quadrato passo dopo passo. 25x^2-13x+36. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=25, b=-13 e c=36. 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=25, b=-\frac{13}{25}x e c=\frac{36}{25}. 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=25, b=-\frac{13}{25}x, c=\frac{36}{25}, x^2+b=x^2-\frac{13}{25}x+\frac{36}{25}+\frac{169}{2500}-\frac{169}{2500}, f=\frac{169}{2500} e g=-\frac{169}{2500}. Applicare la formula: \frac{a}{b}c=\frac{ca}{b}, dove a=13, b=50, c=-1, a/b=\frac{13}{50} e ca/b=- \frac{13}{50}.
