Question

Si x+y=4 y x· y=1 ,entonces el valor de x^2+3xy+y^2 esSHOW LESS0

Solution

Respuesta: $x^{2}+3xy+y^{2}=16$.

Paso 1: Calculamos $x^{2}+3xy+y^{2}$. Paso 2: Sustituimos $x^{2}+3xy+y^{2}$ por $(x+y)^{2}$. Paso 3: Utilizamos la identidad $(x+y)^{2}=x^{2}+2xy+y^{2}$. Paso 4: Sustituimos $x+y=4$ en $(x+y)^{2}$. Paso 5: Obtenemos $(x+y)^{2}=4^{2}=16$.
