Question

ayudenme por favor es para hoy dia.

Answer 1

Respuesta:

Paso 1

${(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab \\ {(6)}^{2} = {a}^{2} + {b}^{2} + 2(6) \\ 36 - 12 = {a}^{2} + {b}^{2} \\ 24 = {a}^{2} + {b}^{2}$

Paso 2

$(a - b)^{2} = {a}^{2} + {b}^{2} - 2ab \\ (a - b)^{2} = 24 - 2(6) \\ (a - b)^{2} = 12 \\ a - b = \sqrt{12} \\ a - b = 2 \sqrt{3}$
