To solve a polynomial inequality, it is required to first change the inequality sign to an equal sign and then solve the resulting equation.
The given inequality is:
[tex]x^2+9x+8>0[/tex]
Change the inequality sign to the equal sign to get the resulting equation to solve for:
[tex]x^2+9x+8=0[/tex]
The graph of this equation forms the boundary curve of the solution region in the cartesian plane.
Hence, the real solutions of this equation are called the boundary points.
Answers:
