How do I find the real zeros and plot the sufficient points?

Question

Find the real zeros of the polynomial f(t)=1/4(t^2-2t+14) and plot the sufficient solution points from -4 to 6

Answer 1

The function f(t)=1/4(t²-2t+14) doesn't have any real zeros.

Both roots are complex numbers.

They can be found using the Quadratic formula:

t=1+i√13

t=1-i√13
