Impara online a risolvere i problemi di passo dopo passo. Solve the quadratic equation j^2+28j=-43. Applicare la formula: x^2+bx=x^2+bx+\left(\frac{b}{2}\right)^2-\left(\frac{b}{2}\right)^2, dove b=28, bx=28j, x=j, x^2+bx=j^2+28j e x^2=j^2. Applicare la formula: x^2+bx+f+g=\left(x+\sqrt{f}sign\left(b\right)\right)^2+g, dove b=28, bx=28j, f=196, g=-196, x=j, x^2+bx=j^2+28j+196-196 e x^2=j^2. Applicare la formula: x+a=b\to x+a-a=b-a, dove a=-196, b=-43, x+a=b=\left(j+14\right)^2-196=-43, x=\left(j+14\right)^2 e x+a=\left(j+14\right)^2-196. Applicare la formula: x+a+c=b+f\to x=b-a, dove a=-196, b=-43, c=196, f=196 e x=\left(j+14\right)^2.
