Impara online a risolvere i problemi di completare il quadrato passo dopo passo. 3m^2+130m+1200. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=3, b=130, c=1200 e x=m. 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=3, b=\frac{130}{3}m, c=400 e x=m. 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=3, b=\frac{130}{3}m, c=400, x^2+b=m^2+\frac{130}{3}m+400+\frac{4225}{9}-\frac{4225}{9}, f=\frac{4225}{9}, g=-\frac{4225}{9}, x=m e x^2=m^2. Applicare la formula: \frac{a}{b}+c=\frac{a+cb}{b}, dove a/b+c=\left(m+\frac{65}{3}\right)^2+400-\frac{4225}{9}, a=-4225, b=9, c=400 e a/b=-\frac{4225}{9}.
