Question

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

Answer 1

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

Explanation:

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
