Inequality of Two Variables, Test Point Method
A
The steps for solving a linear inequality (e.g. y > 2x+ 3) , "
graphically with the test point method are: , '
1) Plot the boundary line (e. g. y = 2X + 3). Plot a solid line . ,
if the inequality contains
Quadratic Formula Factoring: Example, Case 2-Not Factorable
Factor the quadratic equation
2x2 - 3x + 10 = 0
using the quadratic formula.
Since a=2, b=-3 and c=10, substitution
into the quadratic formula
-b:\lb2-4ac
