Impara online a risolvere i problemi di passo dopo passo. Solve the quadratic equation a^2+16a=-15. Applicare la formula: x^2+bx=x^2+bx+\left(\frac{b}{2}\right)^2-\left(\frac{b}{2}\right)^2, dove b=16, bx=16a, x=a, x^2+bx=a^2+16a e x^2=a^2. Applicare la formula: x^2+bx+f+g=\left(x+\sqrt{f}sign\left(b\right)\right)^2+g, dove b=16, bx=16a, f=64, g=-64, x=a, x^2+bx=a^2+16a+64-64 e x^2=a^2. Applicare la formula: x+a=b\to x+a-a=b-a, dove a=-64, b=-15, x+a=b=\left(a+8\right)^2-64=-15, x=\left(a+8\right)^2 e x+a=\left(a+8\right)^2-64. Applicare la formula: x+a+c=b+f\to x=b-a, dove a=-64, b=-15, c=64, f=64 e x=\left(a+8\right)^2.
