SOLVING SYSTEMS OF EQUATIONS IN THREE VARIABLES
When solving systems of equation with three variables we use the elimination method or the
substitution method to make a system of two equations in two variables.
Example
Solve the systems of equations (this
SOLVE EQUATIONS AND SIMPLIFY EXPRESSIONS
In algebra 1 we are taught that the two rules for solving equations are the addition rule and the
multiplication/division rule.
The addition rule for equations tells us that the same quantity can be added to both s
Long Division of a Polynomial by a Binomial
Long division of a polynomial by a binomial is carried out in essentially the same manner as long
division of two integers with no variables:
Divide the highest degree term of the polynomial by the highest degre
Synthetic Division
Long division is useful with the remainder and factor theorems, but long division can be time
consuming. To divide a polynomial by a binomial and compute the remainder, we can also use
synthetic division. We can only divide by a binomia
