Impara online a risolvere i problemi di completare il quadrato passo dopo passo. 9c^2+c+25. Applicare la formula: ax^2+x+c=a\left(x^2+\frac{1}{a}x+\frac{c}{a}\right), dove a=9, c=25 e x=c. 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=9, b=\frac{1}{9}c, c=\frac{25}{9} e x=c. 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=9, b=\frac{1}{9}, c=\frac{25}{9}, bx=\frac{1}{9}c, f=\frac{1}{324}, g=-\frac{1}{324}, x=c, x^2+bx=c^2+\frac{1}{9}c+\frac{25}{9}+\frac{1}{324}-\frac{1}{324} e x^2=c^2. Applicare la formula: x\left(a+b\right)=xa+xb, dove a=\left(c+\frac{1}{18}\right)^2, b=\frac{899}{324}, x=9 e a+b=\left(c+\frac{1}{18}\right)^2+\frac{899}{324}.
