2х² + 5 + 3 = 0
2х² + 8 = 0
2(х² +4)=0 |÷2
х² +4 =0
x² = - 4 уравнение не имеет вещественных корней
х² - 5х + 3 =0
D=(-5)² - 4*1*3 = 25 - 12 = 13
D>0 два корня уравнения
х₁ = (5 - √13)/2 = 1/2 * (5 -√13) = 0,5(5-√13) = 2,5 - 0,5√13
х₂ = (5 +√13)/2= 2,5 +0,5√13

2х² + 5 + 3 = 02х² + 8 = 0
2(х² +4)=0 |÷2
х² +4 =0
x² = - 4 уравнение не имеет вещественных корней
х² - 5х + 3 =0
D=(-5)² - 4*1*3 = 25 - 12 = 13
D>0 два корня уравнения
х₁ = (5 - √13)/2 = 1/2 * (5 -√13) = 0,5(5-√13) = 2,5 - 0,5√13
х₂ = (5 +√13)/2= 2,5 +0,5√13
