Impara online a risolvere i problemi di passo dopo passo. 25x^2-2x+16. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=25, b=-2 e c=16. 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{2}{25}x e c=\frac{16}{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{2}{25}x, c=\frac{16}{25}, x^2+b=x^2-\frac{2}{25}x+\frac{16}{25}+\frac{1}{625}-\frac{1}{625}, f=\frac{1}{625} e g=-\frac{1}{625}. Applicare la formula: \frac{a}{b}c=\frac{ca}{b}, dove a=1, b=25, c=-1, a/b=\frac{1}{25} e ca/b=- \frac{1}{25}.
