Impara online a risolvere i problemi di equazioni quadratiche passo dopo passo. Solve the quadratic equation q^2+22q=-85. Applicare la formula: x^2+bx=x^2+bx+\left(\frac{b}{2}\right)^2-\left(\frac{b}{2}\right)^2, dove b=22, bx=22q, x=q, x^2+bx=q^2+22q e x^2=q^2. Applicare la formula: x^2+bx+f+g=\left(x+\sqrt{f}sign\left(b\right)\right)^2+g, dove b=22, bx=22q, f=121, g=-121, x=q, x^2+bx=q^2+22q+121-121 e x^2=q^2. Applicare la formula: x+a=b\to x+a-a=b-a, dove a=-121, b=-85, x+a=b=\left(q+11\right)^2-121=-85, x=\left(q+11\right)^2 e x+a=\left(q+11\right)^2-121. Applicare la formula: x+a+c=b+f\to x=b-a, dove a=-121, b=-85, c=121, f=121 e x=\left(q+11\right)^2.
