Impara online a risolvere i problemi di passo dopo passo. Solve the quadratic equation x^2-26x=-15. Applicare la formula: x^2+bx=x^2+bx+\left(\frac{b}{2}\right)^2-\left(\frac{b}{2}\right)^2, dove b=-26, bx=-26x e x^2+bx=x^2-26x. Applicare la formula: x^2+bx+f+g=\left(x+\sqrt{f}sign\left(b\right)\right)^2+g, dove b=-26, bx=-26x, f=169, g=-169 e x^2+bx=x^2-26x+169-169. Applicare la formula: x+a=b\to x+a-a=b-a, dove a=-169, b=-15, x+a=b=\left(x-13\right)^2-169=-15, x=\left(x-13\right)^2 e x+a=\left(x-13\right)^2-169. Applicare la formula: x+a+c=b+f\to x=b-a, dove a=-169, b=-15, c=169, f=169 e x=\left(x-13\right)^2.
