What are the values of x in the equation 4x2 4x – 3 = 0? x = –1.5, 0.5 x = –0.5, –1.5 x = x =?

4x^2+ 4x – 3 = 0

Using Quadratic Formula:

x = [-4 + sqrt(16+48)]/8
or
x = [-4 - sqrt(16+48)]/8

Solving First equation:
x = [-4 + sqrt(16+48)]/8
   = -4+8/8
   = 0.5

Solving Second equation:
x = [-4 - sqrt(16+48)]/8
   = - 4 - 8 /8
   = -12/8
   = -1.5
