no real number solution.

There are no real solutions for the equation .

Step-by-step explanation:

For a quadratic equation given by

The number of real solutions are determined by discriminant D.

D=

if D>0 then the roots are real and distinct

if D=0 then roots are real and equal

if D<0 then real roots do not exist.

In this case,

a=1 b=5 and c=7

Since D<0, there are no real solutions.

it would rotate about 180 degrees.
