Impara online a risolvere i problemi di equazioni quadratiche passo dopo passo. Solve the quadratic equation r^2-10r=-17. Applicare la formula: x^2+bx=x^2+bx+\left(\frac{b}{2}\right)^2-\left(\frac{b}{2}\right)^2, dove b=-10, bx=-10r, x=r, x^2+bx=r^2-10r e x^2=r^2. Applicare la formula: x^2+bx+f+g=\left(x+\sqrt{f}sign\left(b\right)\right)^2+g, dove b=-10, bx=-10r, f=25, g=-25, x=r, x^2+bx=r^2-10r+25-25 e x^2=r^2. Applicare la formula: x+a=b\to x+a-a=b-a, dove a=-25, b=-17, x+a=b=\left(r-5\right)^2-25=-17, x=\left(r-5\right)^2 e x+a=\left(r-5\right)^2-25. Applicare la formula: x+a+c=b+f\to x=b-a, dove a=-25, b=-17, c=25, f=25 e x=\left(r-5\right)^2.
