2. Solving Quadratic Equations when they
do NOT equal ZERO
• So far all the quadratic equations we’ve solve have
been equal to zero but not all are so nice. If they
don’t equal zero, make them equal to zero!
• View this Cool Math website to how to solve
Quadratic Equations when the original equation is
not equal to 0.
• There are 3 pages to view.
• Complete the Your Turn problems in your notebook
and check your answers on the next slide.

45. Do you want to Play a GAME?
• Check your knowledge on solving Quadratic
Equations by playing Jeopardy. Ok, technically it’s
called Challenge Board but it’s the same idea!
• You have the option to play alone or against a
friend or maybe a family member!
• You could even arrange a time with a classmate to
meet on Pronto to play. Try the App Share feature
to see the same game board!
• Finding the x-intercepts is the same as solving!
46. Fantastic Job!
• You’ve finished reviewing Solving Quadratic
Equations Part 2.
• Exit and proceed
to the Homework
Assignment.
