Impara online a risolvere i problemi di completare il quadrato passo dopo passo. 10y^2+17y+-20. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=10, b=17, c=-20 e x=y. 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=10, b=\frac{17}{10}y, c=-2 e x=y. 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=10, b=\frac{17}{10}y, c=-2, x^2+b=y^2+\frac{17}{10}y-2+\frac{289}{400}-\frac{289}{400}, f=\frac{289}{400}, g=-\frac{289}{400}, x=y e x^2=y^2. Applicare la formula: \frac{a}{b}+c=\frac{a+cb}{b}, dove a/b+c=\left(y+\frac{17}{20}\right)^2-2-\frac{289}{400}, a=-289, b=400, c=-2 e a/b=-\frac{289}{400}.
