Question

Efectuati (√3x+√2y)²

Answer 1

$3 {x}^{2} + 2 \sqrt{6} xy + 2 {y}^{2}$ dupa formula(a+b) totul la patrat este = a patrat + 2ab + b patrat

Answer 2

${( \sqrt{3}x + \sqrt{2}y ) }^{2}$

$= {( \sqrt{3}x) }^{2} + 2 \times \sqrt{3} x \times \sqrt{2} y + {( \sqrt{2} y)}^{2}$

$= 3 {x}^{2} + 2 \sqrt{6} xy + 2 {y}^{2}$
