x=(1+isqrt(11))/4,(1-isqrt(11))/4

Explanation:

Let's find the values for variables a, b, and c.

y=4x^2-2x+3

a=4,b=-2,c=3

Let's plug these numbers into the equation.

x=(-b±sqrt(b^2-4ac))/(2a)=(-(-2)±sqrt((-2)^2-4(4)(3)))/(2(4))

Now we can solve for the zeros of the equation.

x=(2±sqrt(4-48))/8 ->

x=(2±sqrt(-44))/8 ->

x=(2±2isqrt(11))/8 ->

x=(1±isqrt(11))/4

Your zeroes will be imaginary. The zeroes are (1+isqrt(11))/4 and (1-isqrt(11))/4.
