Question

How do you use the quadratic formula to solve the equation, `1/2x^2 + 3x - 5 = 0`?

Answer 1

`a=1/2, b=3, c=-5 -> x= (-b+- sqrt(b^2-4ac))/(2a) =(-3+- sqrt(3^2-4(1/2)(-5)))/(2(1/2)) = -3+-sqrt19`

Explanation:

Determine a , b, and c and then substitute it into the quadratic formula above and solve for x
