X = 12

Explicación:

(x + 1)² = x²+ 13

x² + 1 = x² + 13

x² - x² = 13 - 1

X = 12

Answer 2

Respuesta:

x=6

Explicación paso a paso:

(x + 1)² = x²+ 13

$x^{2} +2x+1=x^{2} +13\\\\x^{2} -x^{2} +2x=13-1\\\\2x=12\\\\x=\frac{12}{2} \\\\x=6$

Comprobación

$(6+1)^{2} =6^{2} +13\\\\7^{2} =36+13\\\\49=49$
