Impara online a risolvere i problemi di passo dopo passo. Solve the quadratic equation x^2+2x=1. Applicare la formula: x^2+bx=x^2+bx+\left(\frac{b}{2}\right)^2-\left(\frac{b}{2}\right)^2, dove b=2, bx=2x e x^2+bx=x^2+2x. Applicare la formula: x^2+bx+f+g=\left(x+\sqrt{f}sign\left(b\right)\right)^2+g, dove b=2, bx=2x, f=1, g=-1 e x^2+bx=x^2+2x+1-1. Applicare la formula: x+a=b\to x+a-a=b-a, dove a=-1, b=1, x+a=b=\left(x+1\right)^2-1=1, x=\left(x+1\right)^2 e x+a=\left(x+1\right)^2-1. Applicare la formula: x+a+c=b+f\to x=b-a, dove a=-1, b=1, c=1, f=1 e x=\left(x+1\right)^2.
