Although the equation `x^2 = -81` does not have any real solutions, its still a pure quadratic equation.Math Blogger™https://www.blogger.com/profile/07750158674158091943noreply@blogger.comtag:blogger.com,1999:blog-2490105929626066237.post-74622193466339136552014-09-15T20:56:10.803-07:002014-09-15T20:56:10.803-07:00You give two examples that have no real answer.
