Question

3x²+2√15 xy+5y² factorise​

Answer 1

${3x}^{2} + 2 \sqrt{15} xy + {5y}^{2} \\ {( \sqrt{3} x)}^{2} + 2( \sqrt{5}y )( \sqrt{3}x ) + {( \sqrt{5} y)}^{2} \\ {[ \sqrt{3}x + \sqrt{5}y ]}^{2}$

Answer 2

$3 {x}^{2} + \sqrt{15} xy + \sqrt{15} xy + 5 {y}^{2} \\ \\ = > \sqrt{3} x( \sqrt{3} x + \sqrt{5} y) + \sqrt{5} y( \sqrt{3} x + \sqrt{5} y) \\ \\ = > ( \sqrt{3} x + \sqrt{5}y)( \sqrt{3} x + \sqrt{5} y) \\ \\ = > {( \sqrt{3}x + \sqrt{5}y) }^{2}$
