Решите уравнение 1/2х^2+3х+4=0

Ответ

Автор - owlj
 frac{1}{2} x^{2} + 3x + 4=0
а=1/2, b=3, c=4
D= b²-4ac= 3²-4*1/2*4=9-8=1
x1=  frac{-b- sqrt{D} }{2a} =  frac{-3- sqrt{1} }{2* frac{1}{2} } =  frac{-4}{1} = -4
x2=  frac{-b+ sqrt{D} }{2a} =  frac{-3+ sqrt{1} }{2* frac{1}{2} } =  frac{-2}{1} = -2
Ответ: -4; -2
