Question

(x + 6 ) elevado al cuadrado* = (x + 1 ) elevado al cuadrado* +20 (tengo q poner resolucion u explicacion paso a paso me ayudan porfavor doy corona )

Answer 1

Explicación paso a paso:

$(x + 6) {}^{2} = (x + 1) {}^{2} + 20 \\ x {}^{2} + 2 \times x \times 6 + {6}^{2} = ({x}^{2} + 2 \times x \times 1 + {1}^{2}) + 20 \\ {x}^{2} + 12x + 36 - 20 = x {}^{2} + 2x + 1 \\ {x}^{2} - {x}^{2} + 12x - 2x = 1 - 16 \\ 10x = -15 \\ x = -15 \div 10 \\ x = -\frac{3}{2}$
