Question

y²+2√3y+3=0 by factorsation method

Answer 1

$y {}^{2} + 2 \sqrt{3} y + 3 = 0$

$y {}^{2} + \sqrt{3} y + \sqrt{3} y + 3 = 0$

$y(y + \sqrt{3} ) + \sqrt{3} (y + \sqrt{3} ) = 0$

$(y + \sqrt{3} )(y + \sqrt{3} ) = 0$

$y = - \sqrt{3} \: \: \: and - \sqrt{3}$



Regards

Answer 2

y² + 2√3y + 3 = 0

=> y² + (√3 + √3)y + 3 = 0

=> y² + √3y + √3y + 3 =0

=> y(y +√3) + √3(y + √3) = 0

=> (y + √3)(y+√3) =0

By zero product rule,

y = -√3


I hope this will help you
