Answer

Discriminant = -44; no real solution and 2 imaginary solutions

Work Step by Step

$4x^2-2x+3=0$ Plug the coefficients into the discriminant of the quadratic formula. $a=4, b=-2, c=3$ $\sqrt {b^2-4ac}$ $\sqrt {(-2)^2-4(4)(3)}$ $\sqrt {4-48}$ $\sqrt {-44}$ Since the discriminant is less than $0$, the equation has no real solution and two imaginary solutions.
