Example Question #11 : Understanding Quadratic Equations
Solve the equation for .
Cross multiply.
Set the equation equal to zero.
Factor to find the roots of the polynomial.
and
Example Question #2 : Foil
Evaluate
In order to evaluate one needs to multiply the expression by itself using the laws of FOIL. In the foil method, one multiplies in the following order: first terms, outer terms, inner terms, and last terms.
Multiply terms by way of FOIL method.
Now multiply and simplify.
