10. Solve the Quadratic Eq.

11. When solving equations,
a good idea is to try to set the equation
equal to zero, and factor the expression
into a product.
This allows us to take advantage of
the Zero Product Property.

13. Solve the Quadratic Eq.

14. 1.7a Quadratic Equations
Another important property needed to
solve quadratics is the
“Square-Root Property”
