What is the quadratic formula of #3x² + 10x – 2 = 0#?

1 Answer

#x= -10 + or - sqrt((10^2 -4 (3)(-2))/ (2 (3))#


I'm assuming you want to know what the quadratic formula would look like for this particular equation. The quadratic formula is#x= -b pm sqrt((b^2 -4ac)/(2a))#.
If the discriminant (#b^2-4ac#) is greater than zero, there will be two solutions: -b + everything inside the radical and -b - everything inside of the radical.
In this equation:
a (the coefficient of the squared term)= 3
b (the coefficient of the linear term)= 10
c (the constant)= -2
