The roots of f(x) = 2x^2-3x-2 are required.
Solve the quadratic equation 2x^2 - 3x - 2 = 0.
The roots of a quadratic equation ax^2 + bx + c = 0 are given by `(-b+-sqrt(b^2-4ac))/(2a)`
For the equation 2x^2 - 3x - 2 = 0, a = 2, b = -3 and c = -2, the roots of the equation are:
`(-(-3)+-sqrt((-3)^2-4*2*-2))/(2*2)`
`(3+-sqrt(9 + 16))/4`
`(3+-sqrt 25)/4`
`(3+- 5)/4`
8/4 and -2/4
2 and -1/2
The roots of f(x) = 2x^2-3x-2 are 2 and -1/2
