Chapter 14
Taking on Quadratic Equations
A quadratic equation has the form
The Problems You’ll Work On
In this chapter, you work with quadratic equations in the following ways:
Applying the square root rule
Solving equations by using factoring and the multiplication property of 0
Using the quadratic formula and simplifying radicals when possible
Solving quadratic equations by completing the square
Introducing imaginary solutions
Simplifying complex solutions with or without radicals
What to Watch Out For
Don’t get too caught up in your work and neglect the following:
Applying the square root rule only when you have ax2 = c
Using the correct signs when applying the multiplication property of 0
Watching the order of operations when simplifying the work in the quadratic formula
Simplifying the fraction correctly in the quadratic formula
Pulling out the square root of –1 when determining imaginary roots
