Impara online a risolvere i problemi di passo dopo passo. Solve the inequality 3x^2+4x>=0. Applicare la formula: ax^2+x+c=a\left(x^2+\frac{1}{a}x+\frac{c}{a}\right), dove a=3 e c=4. 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{1}{3}x e c=\frac{4}{3}. 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=3, b=\frac{1}{3}, c=\frac{4}{3}, bx=\frac{1}{3}x, f=\frac{1}{36}, g=-\frac{1}{36} e x^2+bx=x^2+\frac{1}{3}x+\frac{4}{3}+\frac{1}{36}-\frac{1}{36}. Applicare la formula: ax\geq b=x\geq \frac{b}{a}, dove a=3, b=0 e x=\left(x+\frac{1}{6}\right)^2+\frac{47}{36}.
