Impara online a risolvere i problemi di passo dopo passo. 49x^2-84x+-36. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=49, b=-84 e c=-36. 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=49, b=-\frac{12}{7}x e c=-\frac{36}{49}. 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=49, b=-\frac{12}{7}x, c=-\frac{36}{49}, x^2+b=x^2-\frac{12}{7}x-\frac{36}{49}+\frac{36}{49}-\frac{36}{49}, f=\frac{36}{49} e g=-\frac{36}{49}. Applicare la formula: \frac{a}{b}c=\frac{ca}{b}, dove a=6, b=7, c=-1, a/b=\frac{6}{7} e ca/b=- \frac{6}{7}.
