Question

-8+-корень 12 дробь 2 *1

Answer 1

$x_{1}= frac{-8- sqrt{12} }{2*1} =frac{-8- sqrt{4*3} }{2} =frac{-8-sqrt{2^{2}*3} }{2}=frac{-8- 2sqrt{3} }{2}=frac{-10sqrt{3} }{2}=-5 sqrt{3} \ x_{2}= frac{-8+ sqrt{12} }{2*1} =frac{-8+ sqrt{4*3} }{2} =frac{-8+sqrt{2^{2}*3} }{2}=frac{-8+2sqrt{3} }{2}=frac{-6sqrt{3} }{2}=-3 sqrt{3}$
