Impara online a risolvere i problemi di completare il quadrato passo dopo passo. 26y^2+y+-1. Applicare la formula: ax^2+x+c=a\left(x^2+\frac{1}{a}x+\frac{c}{a}\right), dove a=26, c=-1 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=26, b=\frac{1}{26}y, c=-\frac{1}{26} e x=y. Applicare la formula: a\left(x^2+bx+c+f+g\right)=a\left(\left(x+\sqrt{f}sign\left(b\right)\right)^2+c+g\right), dove a=26, b=\frac{1}{26}, c=-\frac{1}{26}, bx=\frac{1}{26}y, f=\frac{1}{2704}, g=-\frac{1}{2704}, x=y, x^2+bx=y^2+\frac{1}{26}y-\frac{1}{26}+\frac{1}{2704}-\frac{1}{2704} e x^2=y^2. Applicare la formula: x\left(a+b\right)=xa+xb, dove a=\left(y+\frac{1}{52}\right)^2, b=-\frac{105}{2704}, x=26 e a+b=\left(y+\frac{1}{52}\right)^2-\frac{105}{2704}.
