Pure quadratic equation

Solve pure quadratic equation
10x2+3=0 -10x2 +3 = 0
.

Result

x1 =  0.55
x1 =  -0.55

Solution:

<tex>10x2+3=0</tex> 10x2=3 x2=0.3 x1=0.3=0.55<tex> -10x^2 +3 = 0</tex> \ \\ -10x^2 = -3 \ \\ x^2 = 0.3 \ \\ x_1 = \sqrt{ 0.3 } = 0.55
x2=0.3=0.55x_2 = - \sqrt{ 0.3 } = -0.55



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
