Impara online a risolvere i problemi di equazioni quadratiche passo dopo passo. Solve the quadratic equation 8/15x^2+0.24x+-0.216=0. Applicare la formula: ax^2+bx+c=0\to x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}, dove a=\frac{8}{15}, x^2a=\frac{8}{15}x^2, b=\frac{6}{25}, x^2a+bx=0=\frac{8}{15}x^2+0.24x-0.216=0, c=-0.216, bx=0.24x e x^2a+bx=\frac{8}{15}x^2+0.24x-0.216. Applicare la formula: a=b\to a=b, dove a=x e b=\frac{-0.24\pm \sqrt{0.24^2-4\cdot -0.216\cdot \left(\frac{8}{15}\right)}}{2\cdot \left(\frac{8}{15}\right)}. Applicare la formula: x=\frac{b\pm c}{f}\to x=\frac{b+c}{f},\:x=\frac{b-c}{f}, dove b=-\frac{6}{25}, c=\frac{18}{25} e f=\frac{16}{15}. Applicare la formula: a+b=a+b, dove a=\frac{18}{25}, b=-\frac{6}{25} e a+b=-0.24+0.72.
