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

45. Do you want to Play a GAME?
โข Check your knowledge on solving Quadratic
Equations by playing Jeopardy. Ok, technically itโs
called Challenge Board but itโs the same idea!
โข You have the option to play alone or against a
friend or maybe a family member!
โข 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!
โข Finding the x-intercepts is the same as solving!
