Engaging in discussion and explanation of mathematical ideas is crucial to understanding and doing math successfully.
Prompt: One of your classmates, Jon, solved the following quadratic equation: 2x? + 8x – 7 = 0. Jon used the quadratic formula to get the following
two solutions (answers): x =
-2 + 2/30 and x =
:-2 – 2/30.
Jon is confused because he is sure that he applied the quadratic formula correctly, but his answers don't check in the original equation. Jon needs your
help to understand the mistake he made.
You ask to see his work and he shows you:
